Transferring Data on PC
Transferring data
Moving data between your old and new PC has never been so simple. This guide shows you how with File and Settings Transfer Wizard
Transferring data
Having decided to upgrade to a newer PC, the euphoria of being the proud owner of a spanking new system can suddenly be cut short. The problem is, there’s all that data that needs to be transferred from your old machine to your new one. It can be difficult trying to decide which files and folders are to be copied over, and then there are the program settings for the individual applications that you have installed. Take a moment to think about the other items too, including email messages and account information, not to mention your Internet connection settings. All these will need to be moved from one PC to the other. If you’re in the position of upgrading to a Windows XP system then you should make full use of the ‘File and Settings Transfer Wizard.’ This built-in utility makes light work of moving important data and settings from one PC to another.
The File and Settings Transfer Wizard will work with any Windows operating system. It will enable you to transfer data from Windows 95 upwards, restoring files and settings in the both the Home and Professional Editions of Windows XP. Your data can be moved using a variety of methods. For example, you can use a direct connection between the two PCs, perhaps a network or a cable link. Alternatively, you can create a file that contains all the transferable data and save it to a hard drive partition or removable media such as a recordable CD/DVD or Zip disk.
Full control
The settings within the wizard enable you to back up as much or as little of your existing data as you want. Not only will you be able to transfer your files and folders, but it’s also possible to incorporate individual user settings. Details of desktop display, wallpaper and themes, folder settings and Internet connection information can all be saved. You can also copy over elements of Internet Explorer that you’ll require on your new PC. These include Favorites, cookies and security certificates. Information contained within Outlook and Outlook Express, such as email settings and address books can also be transferred. However, if you’ve created Identities in Outlook Express, any messages and folders won’t be copied over separately. Instead, all messages will end up being grouped together.
One aspect of the File and Settings Transfer Wizard that you’ll find particularly useful, enables Registry settings and preferences from applications to be transferred. It works well for both Microsoft and non-Microsoft programs. Should the wizard encounter an application that it’s unable to deal with then you’ll be informed accordingly.
Getting started
In order to transfer data from an old PC to your new system you’ll need to have your original Windows XP installation CD to hand. When the menu appears, choose ‘Perform Additional Tasks’ and select ‘Transfer Files and Settings.’ Click Next and under ‘Select a Transfer Method’ you’ll have to choose how the information is to be copied over. Having both machines on a network is the easiest method of transferring your data. Without some kind of direct connection you should select ‘Floppy drive or other removable media’. This will enable you to use media such as a recordable CD/DVD.
With your chosen method selected, click Next and decide exactly want you want to back up. Select ‘Both files and settings’ as it’s best to be as thorough as possible and remember to check the option that will enable you to make your own selections. On the next screen you’ll see specific files, folders and settings that are to be backed up. Leave everything selected unless you’re sure there’s something there that you don’t need. The default selections will ensure that the items, My Documents and My Pictures are selected for back up. However, you’ll need to make sure that any folders you’ve created are included in the transfer process. To do this click Add Folder and Add File and select exactly what you want. Once you’re sure you’ve got everything you need for the transfer click on Next and wait while the information is collected from your system. This may take a while if there’s a lot of content coming over from your old PC.
Don’t worry if the amount of data you’re transferring exceeds the capacity of the removable media you’ve decided to use. The File and Settings Transfer Wizard will automatically span the backed up data over as many disc sets that you require. This will enable you to restore the information with ease. With the transfer of data completed, click on Finish. Now you’re ready to restore the data on your new PC. Having got this far you’re probably wondering if this Transfer Wizard could be used as a regular back-up tool, even though its intended use is to transfer data from one PC to another. Although, Windows XP comes with its own dedicated back-up utility, the File and Settings Transfer Wizard is ideal if you want to back up specific items and system configuration settings.
Using the File and Settings Transfer Wizard
* Place the original Windows XP CD in the drive of your old PC, choose ‘Perform Additional Tasks’ and choose ‘Transfer Files and Settings’ then click Next. Select Old PC then under ‘Select a Transfer Method’ choose how you want to copy the info.
* If space of media capacity is at a premium then Settings only should be your preferred option. The Files only option covers specific folders including the Desktop and My Documents. So, ideally you should choose ‘Both files and settings’.
* Choose to select from a ‘Custom list of files’ and you can click Add Setting, Add Folder, Add File and Add File Type, to include your own items. Having selected all the items to be transferred, click Next and wait for the process to complete.
* With everything now backed up it’s time to move over to the Windows XP machine. Click Start -> All Programs -> Accessories -> System Tools -> File and Settings Transfer Wizard. Select the New computer option, click Next and wait.
* Choose the final option ‘I have already collected my files and settings from my old computer’ and click Next. Select the location of the stored files whether it’s cable, removable media or drive location and click Next.
* It’s not possible to be selective with the info that you import on to your new machine. All the data and application configuration settings will be transferred in one go. If there’s anything you don’t need you’ll have to delete it afterwards
Get unlimited bandwidth from your host for free
Get unlimited bandwidth from your host for free
NOTE: This applies only to specific hosting companies, due to the
specific setup needed and does have its drawbacks.
While setting up hosting space with a specific company I often deal
with, I noticed that they used a shared IP. (IP shared by two or more
websites/domains.) Well, the rates for unlimited bandwidth were
around $50+ per month, which I found unreasonable. I didnt require
much space, and didnt want to be limited to a mere 3 gig of traffic
per month.
Back on track... When setting up the acct, the hosting company needs
to know the domain name so that they can direct it accordingly.
(example: 'http://www.123.4.567.890/~user1/ ,
'http://www.123.4.567.890/~user2/ etc)
At this point you can give a url that doesnt belong to you at all. As
long as the nameservers dont change, that should have absolutly no
negative effects on you or your site whatsoever.
How it works is this:
The host propogates you a certain amount space on its servers, and
monitors the traffic that enters their space through the domain its
registered under. Being that the domain isn't connected to the site
at all, it registers ZERO traffic.
Zero traffic registered = can't possibly go over bandwidth
restrictions
can't possibly go over bandwidth restrictions = free unlimited
bandwidth
Now the problems with this (besides the ethical ones) is that your
host may offer X amount of mail addys with the acct
(you@y...) and these will not work, as the name isnt on their
DNS. However, some domain companies allow you to set it up
regardless. Another problem seems to be strictly cosmetic, but can be
highly problematic... Once you attach the domain you want onto the
site, each page comes up/w the ip/UN the host propagated to your
acct. Its at this point where you have to have a phenominal 10-15
character alphanumerical or better (#, &, etc) pw, or your site will
be vulnerable to attack since the attacker already has your UN. This
only gives attackers a slight advantage as the amount of time it
would take to brute force a 10 character pw @ a rate of 1,000,000 per
second is 10 years. Add numbers and case sensitivity to that and it
becomes approx 26,980 years.
While I'm on it, I may as well add that if you use this method,
obviously you are going to be using the lowest cost hosting plan
available, which in turn will offer the least amount of space. Thats
why free hosts were invented.
Free hosts suck as a general rule. Who wants a site smothered in ads?
However, if you upload all your programs, graphics and other large
files (have a backup of course) to a reliable free host and target
them accordingly from your site you have just freed up a signifigant
amount of space. The only setback/w this is having to keep an index
card or file around/w your pws, as you should never use the same one
twice, and want to use complicated ones.
Downloading Files, Using Archives And Images
So, you've just got a brand new internet connection thingie installed and it can handle up to 1 meg/sec download. But offcourse, no good PC without good software, but you know, good software is very expensive... And on a beautifull sunday morning you see something called Warez. Behold our kingdom and you start drewling a bit untill ur mom comes raging in your room asking for you to put the garbage out. After helping your mom out, the PC and fast inet connection is all yours... And so is the free software.
0x02.0 - packaged files.
As you might know, these software packages are sometimes pretty big in size. To try and reduce the big-file-downloads, the releasers of the package will often use some techniques to reduce the load. Techniques as compressing, archiving and splitting. Read-on if you dont understand these words..
0x02.1 - formats & tools.
If you've been around more than 1 year on the net, you prolly allready know all this but for the knew people I added this anyways...
The basic use of your Windows Operating System is the use of many different files and file-types. One of the most used file-types on the net is ZIP. File-types are also called 'formats'.
An overview:
ZIP A zipped file is a file thats been archived and compressed.
RAR RAR files are commonly used for archiving files; which is putting a large number of files in one file. Compressing is optional. File-splitting is optional.
ACE About the same as a RAR file, just an other format and another application.
I explain this to you because these file-types and coresponding programs are often, you can even use always here, used when you want to download Warez. The programs you download are almost always archived, compressed or bundled in one of the above formats. Keep reading if you didnt knew this
Ok so, now we know the formats of the files were gonna deal with, now the programs.
As you prolly figured out allready, these files arent created by Windows or by hand. Theyre made using specialy designed applications. Ill show you what applications you can use.
WinRAR : My personal favorite. Handles all of the above stated formats and alot, alot more. If you ask for my opinion, I think this is the only program you'll ever need.
WinZIP : This is a specially designed application for handleing ZIPPED files. If you like this one, take it.
WinACE : Another multi-file handling tool. Personal opinion: good for splitting files, way too big for every-day use for decompression.
I'd say: make your choice. I recommend WinRAR because of it's simplicity and effectiveness. But hey, I'm not forcing you. Just read some info on the sites and make ur choice.
Oh yea, one last thing: you'll notice these are all Evaluation versions. I suggest you crack them. Look for a good crack for the right version on: www.cracks.am.
0x02.2 - multi-part archives.
? These files are archived in multiple parts (with one of the applicatiosn mentioned above). Which means the software was zipped or rarred and divided into files of a smaller size then the whole thing together. How do you handle this?
>>> Download all the files to one directory.
>>> Check if all files are there. You can do this by looking at the extensions: *.00, *.01, ... If one's missing, download the missing file again (there are more sofisticated ways to do this but this is the simplest).
>>> Check if the files are about the same size. For example: the *.04 file must be the same size as the *.05 file, unless the 5th file is the last one.
>>> If theres a file with the extension *.RAR, double click it and u can start unpacking the stuff.
>>> If theres no *.RAR, but an *.ACE, do the same, its just an other format.
>>> Once you unarchived the package, you should have a directory full of files from an instalation or program. But its also possible there are, with the archived files, some other things:
- If the software pack is a Warez Group (MYTH, CLASS, Fairlight (FLT), ...) release, check if there's an EXE file with the package called Install.exe. If it's there, you can use that to unpack the files.
- If there's no exe in the package, the files are prolly just ready to be copied to your directory of choice // or ready to be installed.
IMPORTANT : please dont forget to read the NFO file. Its very important. It usually contains all further information needed for you to successfully install the software. You can open it with NFO-file viewers or in Notepad (set font to: terminal, 6 or 9 pts).
Normally, you're all done now and ready to start using the software.
? Ok, do I hear protest? Yes I do. It goes: "Hell, I downloaded a multi-part package but it has NO RAR OR ACE OR ZIP OR ANYTHING!!!! Just files with extensions called *.001; *.002, ..."
Your right. Although the situation is quite different from the situation above, it's really not so different when you look closer. Those files are just unarchived the same way:
>>> Select the first file (*.001).
>>> Right-click it and select 'Extract here...'
Watch the progress bar go! You see, its just the same method. You might notice theres only 2 or 3 files decompressed: ISO or CUE and BIN files. Thats fairly normal. Well talk about handling them in topic 0x03.0...
0x02.3 - one-file downloads.
Ok so the stuff u downloaded was none of above. Conclusion: you downloaded one big file. This happens quite often when you download things from fast-working FTPs.
What you need to do now:
>>> If the file is archived (.rar, .ace, .zip, ...), just unarchive it.
>>> If the file u unrachived is some weird *.ISO or *.CUE file, go to 0x03.0.
>>> If not, just continue the procedure as stated in 0x02.2.
0x03.0 - a clear view on images.
So when youre reading this, u prolly have some files called *.ISO or *.CUE. Offcourse you want to install the software as fast as possible. But, theres a little problem here. Those extensions... What the hell are they... Alienized files? No. Secret CIA files? Nope. You can stop guessing. Ill tell you: those files are image files.
0x03.1 - what are images?
Image files are big files filled with data. Yea, you can say its a sort of archived file. But theres something special about them: they are meant to written on a disc. They were made by special programs so they could be used to write on a CD-R with a writer and specially designed software.
0x03.2 - ISO files.
ISO is the most used image-format on the net. It has become a standard to any commercial cd-writing software to support image-writing capabilities, more specific ISO images.
Conclusion: ISO is just an extension for a specific type of image -file. But how do you install your software? You have 2 ways of dealing with this:
1) Use the file for what is was created: writing it to a CD-R.
2) Extracting the contents of an ISO to a certain directory.
First: how to write them to a CD-R...
>>> Download some CD-R writing software (if you dont have it allready).
>>> Install and crack it.
I recommend Nero Burning Rom. You can download it from WareZone in the Apps section.
>>> Go buy some CD-R's
>>> Fire-up Nero and you can start burning. Im not going to explain you how to use Nero. Read the help file about image writing and you should be fine. You can also use the wizard which is loaded automatically when you boot Nero.
Second: what to do if you dont got a CD-writer....
>>> Download some Image handling software.
I recommend WinISO.
>>> Fire-up WinISO, load your image file and extract it. Again I wont explain how to use WinISO. Check for help files or tutorials on the net, they should give you all the answers you need.
0x03.3 - CUE & BIN files.
CUE and BIN files always come together. The BIN file is comparable with an ISO and the CUE file is just a check, but it is required for any program to write this file correctly. Sometimes, theres an SFV file included. Again this is just a check-up about the file integrity.
You can burn and extract these files the same way i explained in 0x03.2.
0x04.0 - CD Emulation.
Ok, so here's another way to handle ISO images if you don't have a cd-writer.
You can create a virtual cd drive. What's that? That's something you'll see as a new disk drive in your Windows Explorer. This disk drive represents the contents you would see if you would burn the ISO image to cd!
How to create a virtual cd drive? Download DaemonTools !

(I'm IT, I use these codes to trouble shoot hardware issues at my job. Enjoy) cold.gif
BIOS Beep Codes
When a computer is first turned on, or rebooted, its BIOS performs a power-on self test (POST) to test the system's hardware, checking to make sure that all of the system's hardware components are working properly. Under normal circumstances, the POST will display an error message; however, if the BIOS detects an error before it can access the video card, or if there is a problem with the video card, it will produce a series of beeps, and the pattern of the beeps indicates what kind of problem the BIOS has detected.
Because there are many brands of BIOS, there are no standard beep codes for every BIOS.
The two most-used brands are AMI (American Megatrends International) and Phoenix.
Below are listed the beep codes for AMI systems, and here are the beep codes for Phoenix systems.
AMI Beep Codes
Beep Code Meaning
1 beep DRAM refresh failure. There is a problem in the system memory or the motherboard.
2 beeps Memory parity error. The parity circuit is not working properly.
3 beeps Base 64K RAM failure. There is a problem with the first 64K of system memory.
4 beeps System timer not operational. There is problem with the timer(s) that control functions on the motherboard.
5 beeps Processor failure. The system CPU has failed.
6 beeps Gate A20/keyboard controller failure. The keyboard IC controller has failed, preventing gate A20 from switching the processor to protect mode.
7 beeps Virtual mode exception error.
8 beeps Video memory error. The BIOS cannot write to the frame buffer memory on the video card.
9 beeps ROM checksum error. The BIOS ROM chip on the motherboard is likely faulty.
10 beeps CMOS checksum error. Something on the motherboard is causing an error when trying to interact with the CMOS.
11 beeps Bad cache memory. An error in the level 2 cache memory.
1 long beep, 2 short Failure in the video system.
1 long beep, 3 short A failure has been detected in memory above 64K.
1 long beep, 8 short Display test failure.
Continuous beeping A problem with the memory or video.
BIOS Beep Codes
Phoenix Beep Codes
Phoenix uses sequences of beeps to indicate problems. The "-" between each number below indicates a pause between each beep sequence. For example, 1-2-3 indicates one beep, followed by a pause and two beeps, followed by a pause and three beeps. Phoenix version before 4.x use 3-beep codes, while Phoenix versions starting with 4.x use 4-beep codes. Click here for AMI BIOS beep codes.

buid a computer
assemble, repair a computer
Introduction
In this tutorial I will try an teach you how to successfully build your own computer! There are many benefits to building your own computer.
- You get hand's on experience learning how a computer works
- Its a hell of alot less expensive then buying one from a retailer
- Its a hell of alot more reliable than buying one from a retailer being that you hand select QUALITY parts and put it togethor yourself.
- You can do your own tech support no more relying on stupid Best Buy Tech's that don't know the difference between their ass and a hard disk jumper (don't worry I'll tell you what those are later)
Section #1 (What Your Going To Need)
Here we will discuss a list of the parts you need and the best place to purchase them. If you want the best
prices on computer hardware you will definitly want to look online. Unfortunatly (and for some of you very fortunatly
if you know what I mean) this requires the use of a credit card. Below is a general list of the devices you will
need...
- A Computer Case (Something To Put All The Computer Parts Togethor In)
- Should only run you about 50 dollars
- Beware the cheap ones with cheap power supplies they will die in a year
- A Mother Board (Everything Will Be Plugged Into The Mother Board)
- A Floppy Drive and a CDROM (Should Be Obvious)
- A Hard Disk (Come In Many Different Flavors and Quality Levels, Stores All The Information In Your Computer)
- A Video Card (Cheap Stuff, Its What Your Monitor Plugs Into)
- IDE Controller Ribbon
- Miscellaneous Accessories
Next we'll take a look at many of the different options you have when buying these pieces of equipment. Your choice
may vary depending on which Operating Systems you plan on running.
Section #2 (Which Brand And Model Should I Buy?)
We'll lets start with your computer case and move all the way down to Miscellaneous Accessories..
1. Computer Case
You will most certainly need an ATX style case with a quality power supply. How do you tell? Well if the case
is only 15-20 bucks theres a pretty good chance its a crappy power supply.
2. A Mother Board
I suggest a quality ASUS (ATX style to match your computer case) mother board its up to you ask your friends.
I've had bad experiences personally with FIC
mother boards.
3. A Floppy Drive and CDROM
Pretty inexpensive stuff, i'd suggest a Sony Floppy drive and a generic CDROM. Doesn't make too much a difference if your
concerned about getting the best price.
4. Hard Disks
Gets alittle tricky. If you want reliability, high speed transfers, and are willing to run Windows I suggest a Western Digital
or a Seagate ULTRA DMA-66. If your not to concerned with speed and want to run a server with Unix i'd go with a Fujitsu or
a Western Digital. Their farely inexpensive but only transfer in 33 megabit bursts as apposed to the DMA-66 which transfer
in 33 megabit bursts. I don't believe Unix currently supports ULTRA DMA-66, but don't quote me on that. Now there's an even faster
transfer rate available via SCSI Hard Disk Controllers, but i'm not about to go into setting up SCSI controllers in this tutorial.
For now we will stick with IDE Hard Disk controllers.
5. Video Cards
Video cards are cheap and if your not a gamer a plain ole gener Cirrus Logic or STB video card will do fine.
6. IDE Controller Ribbon
You'll need 2 different kinds of IDE Ribbon 2 40 pins for your CDROM and Hard Disk and Another with less pins for your floppy.
You can buy these at any local computer store or order them off the web.
7. Miscellaneous Stuff
You may be interested in adding a sound card, ethernet card, and/or 3DFX card to your system. These are relatively easy to do and
I will explain how to add card's to your mother board later.
Section #3 (Where do I buy all this crap!?)
Well if your looking for the best prices online for computer hardware (and this is my unbiast opinion) i'd suggest going to
http://www.pricewatch.com again ask your friends maybe they know a better place. Pricewatch.com researchs the best prices
on computer hardware.
Section #4 (Lets Assemble!)
This next part is very important so read carefully...
-
First things first get yourself a clean desk to work on.
-
Place your ATX stlye computer case on the desk and slide/lift the top off. Inside should be a bunch of wires coming out
of the power supply in the back and a bunch of wires coming out near the face of the box. -
The next thing your going to want to do is place your mother board inside the case and fasten it in. Their might be
metal coverings covering the holes in the computer case were the parralel ports and serial ports on the mother board
should poke through, go ahead and poke those out with a screw drive so you can fit the mother board in snuggly. Every
Case fastens mother boards in different ways. Some use plastic pegs, some use metal screws. It will hopefully be obvious
which you have to use. -
#4 Once the mother board is mounted properly you will need to fasten the floppy drive, and cdrom into the computer case.
All computer cases store floppy drives differently there maybe a slide out container that you screw them into. You'll
have to make sure that the the floppy drive is right side up (duh!) and that the pins are facing towards the back of the
computer. Installing the CDROM is pretty much the same in all computer cases. Some mounting rails should have come
with your mother board. You need to fasten those to the sides of the CDROM and you should be able to slide it right in
to one of the top bays. -
Insert your Video Card. There are presently about 3 differnet forms of slots on your mother board. PCI, ISA, and AGP.
Video Cards are presently made for all 3 of them. AGP stands for "Accelrated Graphics Port" Video Cards made for this
slot are generally more high tech/performance. PCI's work and so do ISA (Althoug ISA is more Old School). Gee how
do I tell the difference? Well AGP slots more than likely is the only small, brown, slot on your mother board. PCI
you probably have the most of these their white and little longer than AGP. ISA, these are longggg and black, ugly.
Insert your Video Card and snug it in there firmly. Don't force it (duh). -
Time for that evil Hard Disk installation. We'll Hit hooking up the power supplies and Installing the Hard Disk at the
same time just for fun. Insert the Hard Disk In a very much similar way to the way you inserted the floppy disk. But
Before you do make sure that the jumper settings are correct on the back of Har Disk. Most hard disks are shipped in
single mode, but if you want to run multiple hard disks (which we won't discuss) you need to set the jumpers differently.
Jumpers are little metal prongs connected with little jumpers that complete a connection. You figure it out. Anyway
you got your hard disk in now its time to hook up the power supplies. The hard disk and the CDROM have similar power supp
lies. 3 or 4 prong. Hook those funny looking cords coming out of the back of the power supply into your CDROM and Hard
Disk. Theres a smaller one that hooks into your floppy it should be obvious. Theres a big power supply (the biggest one
in the lot usually made of white plastic) It fits into a slot on your mother board, it is the main power supply to your
mother board. Its kind of tricky to get in so be careful. -
Now that you have your Power Supplies hooked up you'll need to connect your Periphrials to your Mother Board. Use the IDE
Controller Ribbon I know you all have. Hey one end goes to your CDROM (make sure the red line on the ribbon "pin 1" is
matched up with the first pin on the back of your CDROM) and the other end goes to your mother board (same deal). The
same goes for your hard disk and yoru floppy. Figure it out its not that difficult. You'll know you did something wrong
when you get a floppy disk fail on boot. -
Finishing touches. Don't forget to connect those nasty wires coming out from behind the face of your computer case to
your mother board. They control the on, off, reset, hard disk activity, and power switch. Every mother board is different
so i hope you have a manual with your mother board. Most specify with 2 or 3 character paraphrases that make no sense.
For Example "PWR SWT" = Power Switch "RST SWT" = Reset Switch. Or even more vague than that.
Section #5 (Testing 1, 2, 3)
Ok your ready to give it a whirl, you'll need to get in your system bios. The "DEL" key should usually get you in.
Get it to autodetect your hard disk. Accept the Setting and Save your Configurations. Install Your OS and your ready to go.
That easy!! Ha! you'll prolly have lots of trouble theres a million resources online to help you. Get to it.
Memory on Computer
Is your PC running slow? Well memory upgrades are about the cheapest upgrade that you can do to improve your computers performance drastically. This will be a easy tutorial to understand so you can pop in your memory and determine from now
on out what you have inside your computer. This will be a step by step guide to install Simms and Dimm memmory. Simms memory slots are small and a whiteish color. Dimm memory slots are longer in length and are black. So please when following this tutorial please do not skip read, read carefully or it could end up costing you money. So enjoy this tutorial from Blacksun.box.sk. And for more hardware installation guides visit Blacksun Research Facility.
I.Supplies needed and costs
Supplies you need will be:
- Memory ($50(32MB)-$200(128MB)) - www.kingston.com - www.crucial.com
- Phillips Screwdriver (Should have)
- Anti-static wrist strap(optional)
II.Steps before installation and preparation
Before we start getting into the installation you should have already looked inside your computer for what type of memory your computer support. If you have 2 or more white slots open means you need 72 pin SIMMS memory. SIMMS must be put
in pairs. DIMM on the other hand can go in by itself, so it doesnt need a pair. Clear a space on a desk or table and unplug your computer and carry the case where it is well lighted. Remove the screws holding the out shell of your case, and remove out shell. Now you should be able to see the motherboard and all the insides. Now look for your memory slots on your mother board, If you can not see them then you might have to move or take some stuff out to be able to move around inside but you probly wont have to. So you know, the box in the top left with red, yellow, and black cables coming out is the power supply.
III.The Installation of the Memory
Ok. Now your ready to install the memory.
If you are installing SIMMs memory then...
Grab one of the sticks of memory and slide it into slot from the top at a 60 degree angle(Ex.\.). Once you have it slid all the way in,push it to a upright position until you hear it click. Now put in its pair. Then re-connect the cables and moniter and turn on the power. On the boot up screen look at the memory count will be like 32838k(32MB) of memory. Make sure its reading the memory. If that number varies significantly from what you were expecting contact manufacturer or dealer you bought your memory from.
If you are installing DIMM memory then...
Grab one of the sticks of DIMM memory and line it up to the DIMM Socket so the grooves in the memory stick are the same on the motherboard. Once lined up push the white arms on the top and bottom of the DIMM socket to a outward position so they are not in the way of the memory. Now press firmly on the top and bottom until the white arms come in locking the memory in place.Then re-connect the cables and moniter and turn on the power. On the boot up screen look at the memory count will be like 32838k(32MB) of memory. Make sure its reading the memory. If that number varies significantly from what you were expecting contact manufacturer or dealer you bought your memory from.
IV.CMOS Check
On boot enter your PC should recognize the memory. Not many systems require you but if its required you will get a error message. Then enter your systems setup.
V.Conclusion
Once windows is booted up check out the new memory and make sure it is working properly. I hope this helped you in the steps of installing or upgrading your new memory. If you have any suggestions or questions feel free to email me. More tutorials to come and soon a HTML version with picture references.

Little about hardware
COMPUTER CASES
There are three major cases in a computer which you might want to know about. One is called an at case which means that the standard for the at case has a two plug supply to the motherboard, a keyboard, and peripheral slots all in standard locations. The second type case is an atx case which has one plug supply to the motherboard, keyboard, com ports, printer ports, and usb ports all in standard locations. The third type is a proprietary case which means there is no standard for what's on it and where they attach. There are four major styles of cases. The first one is a tower and it stands upright and is what most computers are made in now. Their's also desktop, slimline, and proprietary too, but mostly just towers.
MOTHER BOARD
A motherboard is what everything plugs into, and without one you can't do much with your computer. It is what I would call the most important part of your computer.
There are three major types of motherboards. They are at, atx, and proprietary. You will only mostly deal with at and atx. There are four main buses on the motherboard. They are power bus, address bus, data bus, and a control bus. A bus is a bundle of wires that send info through them.
MICROPROCESSORS
Microprocessors are what we would call brains. They think for the computer and most info except for DMA (direct memory access) goes from application etc.. to CPU and then to memory. Most modern CPU chips have 8 registers on them. They are data, address, accumulator, program counter, instructions, flag, alu, and a fpu. Registers are storage places for data, numbers etc… the program counter stores the addresses of the next instructions to be done. The instruction register holds the current instruction. The address register contains memory addresses of the current instruction. The address register contains memory address of the next read or write. The accumulator holds one of the mathematical data to be used or the answer to the previous operation. Data registers hold the second part of the mathematical data for the current operation. Flag registers are special bits that are set individually by certain instructions. That's an into to what is inside the cup. FYI - the wires inside a CPU are smaller than a centimeter. The reason the chip is made so big is so that we can handle it.
HISTORY ON COMPUTER
About the first in home computer made by Intel was an Intel 8088 with a 8 bit data bus, a 20 bit address bus and a 16 bit register. Next inline from Intel was the 8086 with a 16 bit data bus and a 20 bit address bus. Then a 80286 with the same thing as the 8086 but a 24 bit address bus. Then their was a 80386 SX with a 16 bit data bus, 24 bit address bus and a 32 bit register. Next was the 80386 DX with a 32 bit data bus, a 32 bit address bus, and a 32 bit register. Then the 80486 SX with the same as the 80386 DX but a little faster. Then Intel came out with a 80486 DX and also a built in FPU. (floating point unit) What the FPU did was let the CPU be able to do decimals super fast which enabled 3D games to run super fast. Next was the 80486 DX2 which was twice as fast as the 80486 DX, and after that came the 80486 DX4 which was three times as fast as the 80486. Then they introduced the Pentium chip. The Pentium chip had a huge 64 bit data bus, a 32 bit address bus and a 32 bit register. It is estimated that every 6 months technology doubles. So as technology advanced computers will get even faster. (I cant imagine needing anything bigger than my 400 MHz) Hope that didn't bore you do death.
HARD STORAGE
Since most people are familiar with such things as a CD-ROM drive. I wont go scrutinize about hard storage. I will just briefly cover it. Most computers typically have a 3 ½ floppy drive, usually assigned to drive letter A. what a lot of people do not know is that there is 3 types of 3 ½ floppies. There is a double density that formats to 720 kb. Then they came out with a high density disk that formats to 1.44 Mb which is twice as much as the double density disk. After the high density disk came the super density disk which formatted came to 2.8 Mb which as you might have guessed is twice as much as the high density disk. There is also a zip drive that holds 100 Mb's of space but not everybody has one and since a zip disk wont fit in a 3 ½ floppy drive and with the creation of the LS-120 disk which holds 120 Mb and 3 ½ floppy's can fit in LS-120 drives I predict zip drives wont really ever take off. Now about CD-ROMs. There is two major types of CD-ROMs out right now. One is scsi CD-ROM. Scsi cards are usually cheap and if you ever find a CD-ROM out somewhere that is fairly new and very cheap then odds are it is a scsi. The reason they are cheap is because they don't run by their self, u have to have an adapter to go with it and that adapter costs about 50 bucks and most people don't know that when they buy the scsi and that's how scsi sellers make their money. Another brand is ATAPI. ATAPI CD-ROMs plug into the IDE slot and then once plugged in you will have to install the CD-ROM driver and translator and it should work if you use the right driver. There is more proprietary CD-ROM's but most of them plug into the sound card and that can cause problems so I would stay away from scsi and proprietary and go with ATAPI.
PARTITIONS
Every hard drive must be partitioned and formatted before they can be used. You will need a copy of a partition too. At this time fdisk is a good partitioning too. Read the manual that comes with it and it will tell you how to use it. Dos partitions are super easy to make.
INTERRUPTS, DMA's AND IRQS
An interrupt is just like it says, it interrupt's something. I'll give you an example of how it works. Say your in school and your teacher is giving a lecture and somebody raises their hand and the teacher stops the lecture and asks the student what his question is. That is just like a computer interrupt. Lets say that you were connected to the internet. You type in a URL to go to www.yahoo.com and your modem sends out the data to all those DNS servers and then when a DNS server finds the address www.yahoo.com it will send back the information to the modem. Well the modem cant hold all of that info and has to send it to the memory so the modem can get some more info. But first it has to get the attention of the CPU so the CPU can put the info into the memory. So it uses it's interrupt to do this. It sends out a signal saying "hey I need you" (not really but close enough) and the computer sends back to the modem "go ahead and tell me what you need" and then the modem asks where it can store it's info in memory and then the CPU gives it the address to store the info at. Then the modem sends info to the memory using DMA. (direct memory access) DMA means that it can access the memory directly without having to go through the CPU. But sometimes it might have to go to the CPU once just to know where to put the info it has into memory then it can access the memory without any help. So now you know what an interrupt is and what DMA is, but what is an irq? An irq is the order of interrupt assignments in which the accer in. On older computers their was only 8 interrupts
- 0) available
- 1) sound/available
- 2) floppy disk controller
- 3) available
- 4) first DMA Controller
- 5) sound/available
- 6) available
- 7) available
so 0, being the first interrupt and 7 being the last. Now on the newer computer's there is currently 16 irq's.
- 1) system timer
- 2) Keyboard controller
- 8) Real-time clock
- 9) Available
- 10) Available
- 11) Available
- 12) Motherboard mouse port/available
- 13) Math coprocessor/available

This might look out of order but this is the way they come in. I'll explain what this means and how it works now. Lets say you were moving your mouse. Your mouse is irq number 12. Every time you move your mouse it sends out an interrupt 12 to your CPU and says, I need u! Then the CPU will reply back "what do you need" and then the mouse will say, "where am I on the screen and the CPU will tell it "you in position dah dah dah." That's how the irq works, well lets say that your moving your mouse while using your serial port 2. Your mouse has priority over your serial port 2 because your mouse comes first on your irq list. So when your sitting their just swishing your mouse around making a figure eight on your computer, you could be interrupting a function that your computer is doing and it will slow it down a tad.
PC hardware
This contains instructions which are specific for that particular motherboard. Those programs and instructions will remain in the PC throughout its life; usually they are not altered. However, it is possible to get replacement / upgrade BIOS's. Primarily the ROM code holds start-up instructions. In fact there are several different programs inside the start-up instructions, but for most users, they are all woven together. You can differentiate between:
* POST (Power On Self Test)
* The Setup instructions, which connect with the CMOS instructions
* BIOS instructions, which connect with the various hardware peripherals
* The Boot instructions, which call the operating system (DOS, OS/2, or Windows)
Note: Only very old or different OS's are stored on ROM, such as OS/2. This is actually a much more efficient system.
BIOS's are static sensitive, so take care when handling them. They can also be PWord protected... if you ever get round to doing this, don't forget the password. As you don't use the BIOS PWord often, this is easy to do. Don't. it's bloody hard getting the PWord back.
Processors
Processors work on a fetch-execute cycle. each tick of the clock, in theory, they get a bit of data... and by tick of the clock here, we don't mean a second, we mean the tick of a computer clock. Depending on the speed of your processor, this is anywhere from 233 million ticks per second for a 233, to 800 for an overclocked 600MHz Athlon chip.
So, you can get, on your average computer, 400 - 500 bits of data per second. Well, wrong actually... because not every clock tick is taken up by getting the data. Every _fourth_ is. Well, what about every other 3? you ask.. they are taken up with _finding_ the data, _getting_ it, and putting it back. So, you say, your processor runs at a quarter of the speed that in theory it should be able to do? Well, yes. And there's no way around this, unfortunately. But, we can make the clock speed a little faster, and it is the clock speed that dictates the speed of the processor... (within reason).
Therefore, you can set the clock ticks on your 233 to 266, and it'll run at 166 MHz. Yes. Unfortunately, the more clock ticks there are in relation to what your chip is _supposed_ to run at, the hotter it Gets. Therefore, you need to install heatsyncs/fans. In fact, the AMD Athlon 600MHz overclocked to 800MHz, the fastest PC at the time of writing has a minature fridge that cools the chip, which is its own special metal box. The tower-sized case also has a box the size of a mini-tower underneath for the cooling system. ;)
For this increase in temperature of 200MHz, the chip is cooled to -37 degrees centigrade. that's cold. ;) (Note: AMD chips generally run a lot hotter than Intel ones). ((Not a problem unless u have no heatsync)) - see the micron section, below...
The Clock
Now, this fabled clock looks like, in most cases, a small black box on your motherboard. The clock ticks it emitts are in the form of a wave , but a different wave: one that is sqare, and it looks like a castle ramparts. the speed of this is dictated by the MHx setting you set with the Jumpers on your motherboard. The waves look like so: (except slightly more square)
__ _ ____ _ _ ___
_¦ ¦___¦ ¦__¦ ¦_¦ ¦_¦ ¦__¦ ¦__ and etc.
The wave, which never changes, and is always the same, is broadcast throughout your motherboard, and it synchronises all of the things that go on there. For example, when you press the left button in your game of quake, the processor assigns different bits of your computer to do whatever is neccacery to redraw what's on the screen, and tells it to have it done in 3 ticks' time. The same process occurs on the gfx card itself, where the main processor assigns a polygon to each other chip, or whatever. Infact, if you have an old enough computer, you can see it being redrawn on the screen... try it... run a gfx-intensive game on a 486... If the task isn't done in time, then it all falls apart, and the computer crashes. This is why you don't want to buy a dodgy CPU. :) (Get an AMD Athlon!).
The signals sent run around your motherboard, through all of those copper bits, and into the chips, ISA slots, or whatever, and the task gets accomplished.
This signal is sent around the motherboard in that most wonderful of things we all love, Binary. Now, Binary is what Computers communicate with, and it is a DIGITAL thing. Digital. A Much used term.
COmputers are electronic, and therefore, all the signals in them are tiny pulses of electricity. Now, electricity can be one of two things. On... or off. And this is what makes it digital. If it could be half on as well, it would be analogue... But no. It's digital. However, the representation of it in the form of signals down wires is analogue, as a sound in a modem wire can be any of a hundred million different pitches, can't it. Yes. This digital signal is, then, a series of 0's and 1's. Binary. The counting system that we use (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11... etc... ) is Denary. It's Base ten... Binary is Base 2 (and Hexadecimal, which is used, amongst other things, is base 16). Therefore it is perfect for being what these signals are coded in. so each charactor on your screen is represented in your computers RAM by a series of Binary digits. Probably 8. if you go into Windows Calculator, and switch to scientific mode (View>Scientific) you can decode this. For example, 1 in Binary is 00000001. 2 is 00000010. The way this can be decoded is thus:
Each digit in binary represents a quantity of a certain number, just as denary does. In denary, there is a column for 1's, a column for 10's, and a column for 100's. And in Binary, there is a column for 1's, 2's, 4's, 8's, etc. Let me show you:
Denary:
| 100s | 10s | 1s |
| 1 | 0 | 0 |
Here, there is a one in the hundreds column, and therefore, 100 + 0 + 0 (0 and 0 are the other 2 columns) makes 100. SO 1 0 0 in Denary represents 100. (of course, translating 100 --> 100 doesn't work, as denary is used in both cases). In Binary, this works this:
Binary (8-bit -- 8 digits)
| 128 | 64 | 32 | 16 | 8 | 4 | 2 | 1 |
| 1 | 1 | 1 | 1 | 1 | 0 | 1 | 0 |
SO... 128 + 64 + 32 + 16 + 8 + 2 + 1 = 250.
So the Binary number 11111010 = 250. Simple, eh?
It is possible to do addition, subtraction, multiplication, in fact, EVEYTHING that is possible with denary (1--> 10)... I'm not going to explain it because it is simply too complicated. ;) Use Windows Calculator... the radio buttons at the top left switch between number systems.
Chipset
We all know what assembly language is, do we not? It is the programming language that is most native to a computer. The instructions go directly to the chip (more or less). (Assembly actually lays on top of Machine code, which is the real native: Assembler is a more human-friendly version)... Each chip has their own different version of assembler/machine code, called its _chipset_. Each new type of chip comes with an upgraded chipset: for example, the Intel MMX chip incorporated the...wait for it... MMX chipset! There are also chipsets such as 3D!Now. THe most basic of commands between, say, Intel and AMD are the same: they have to be in order for the two to be compatible, but more advanced things are different. This is why Alpha chips are incompatible with windows: The chipset is completely different.
Intel has hitherto been the leader in supplying chip sets to the Pentium motherboard. Therefore, let us just mention their chip sets, which have astronomical names. The Neptune chip set (82434NX) was introduced in June 1994. It replaced the Mercury set (82434LX). In both chip sets, there were problems with the PCI bus. In January 1995 Intel introduced the first Triton, where everything worked. This chip set supports some new features: it supports EDO RAM, and it offers bus master integrated EIDE control and NSP (Native Signal Processing - one of the many new creations, which was soon forgotten).
The sorts of things that new chipsets are used for are varied... for example, The Intel TX Chipset, for example, supports SDRam and UltraDMA (But the TX-set cannot cache above 64 MB RAM, and that is a problem.), while AMD chips have their own special Graphics chipset, which is better for that task.
Microns
The CPUs have doubled their calculating capacity every 18 months. This is called "Moore's Law" and was predicted in 1965 by Gordon Moore. He was right for more than 30 years. The latest CPUs use internal wiring only 0.25 microns wide (1/400 of a human hair). But if Moore's Law has to be valid into the next century, more transistors have to be squeezed onto silicon layers. And now there is a new hope. IBM has for the first time succeeded in making copper conductors instead of aluminum. Copper is cheaper and faster, but the problem was to isolate it from the silicon. The problem has been solved with a new type of coating, and now chips can be designed with 0.13 micron technology. The technology is expected later to work with just 0.05 micron wiring! Texas Instruments announced on August 27th 1998 that they expect 0.07 micron CMOS processing in the year 2001. At the time of writing, AMD chips run at .27 microns (?) and Intel at .33. This explains why AMD chips are hotter, as there is less wire, and therefore more probability of the electrons that the electricity is comprised of hitting the side of the wires, and creating heat.
Hard Drives
Hard drives work in much the same way as a floppy disk does. They can, however, store a much larger capacity of data, and therefore are much more fragile, and compact . For this reason, they are hermetically sealed. NEVER OPEN ONE IF YOU WANT TO USE IT AGAIN. There is, inside, 3 or 4 goldy-brown circular plates on which the data is stored. These are much the same as the ones inside a floppy disk, except that they are not 'floppy' but hard, or stiff. The data is stored on the platters magnetically, which explains why floppy disks have a "keep magnets away from me" warning on boxes u buy them in.
IBM introduced the first hard disk in 1957, when data usually was stored on tapes. The first 305 RAMAC (Random Access Method of Accounting and Control) consisted of 50 platters, 24 inch diameter, with a total capacity of 5 MB, a huge storage medium for its time. It cost $35,000 annually in leasing fees (IBM would not sell it outright) and was twice the size of a refrigerator.
In the early 80s, HD's became the preferred storage medium as opposed to floppy drives (these were previously used due to increased reliability). IBM's PS/2 (one of which I have - yay) was one of the first PCs to be equipped with a Hard drive. I think.
Mice
Mice are, as we all know, Input devices, and as we also know, they tell where you are on the mousemat by moving a ball in the bottom. Which you can see. But how does it read how the ball is moving? Well, inside the mouse are 2 rollers, at 90 degrees to each other. When you move the mouse, u move the ball, and thus the rollers. THe rollers have some little discs on the end of them with slits in, and either side of the disc are light-readers, so that when you move tha ball, the mouse can tell because light flasles on and off in its light reader. There is also a 3rd non-functional roller to keep the ball rolling smoothly. Note: It is perfectly safe to turn your mouse upside down ,. take the ball out and look inside, as long as you don't prod anything too hard (twiddle the rollers by all means, just don't stick bits of paper in there). It is also a good idea to get a blunt knife or screw driver and clean the crud off the rollers every few weeks... it solidifies into little rings around the rollers, and works to the detriment of the mouse. If it isn't cleaned off, it can also, fallinto the mouse, and reak havok with the insides. :) The same sort of crud builds up in keyboards, but is harder to remove. ;)
GFX Cards
A video card is typically an adapter, a removable expansion card in the PC. Thus, it can be replaced! The video card can also be an integral part of the system board...This is the case in certain brands of PCs and is always the case in lap tops. This is not nice, as it is hard to upgrade to a better card. On a OC with a non-removable gfx or sound card, the normal procedure if you _do_ want to replace it is to disable the built-in graphics card using jumpers or dip switches... consult your motherboard manual. ;) Regardless of whether it is replaceable or integrated, it consists of three components:
* A video chip of some brand (ATI, Matrox, S3, Cirrus Logic, or Tseng, to name some of the better known). The video chip creates the signals, which the screen must receive to form an image.
* Some kind of RAM (EDO, SGRAM, or VRAM, which are all variations of the regular RAM). Memory is necessary, since the video card must be able to remember a complete screen image at any time.
* A RAMDAC - a chip converting digital/analog signals.
NOTE: Never buy an S3. Never. Ever. I've had lots, they're all useless. Remember that.
All ordinary graphics cards can show 3D games. That is really no special trick. The problem is to present them smoothly and fast. If the PC’s video card is made for 2D execution only, the CPU must do the entire workload of geometric transformations etc.! And that task can cause even the fastest CPU to walk with a limp. In recent years there has been an enormous development in 3D graphics cards. Let me briefly describe those here.
There are two types of graphics cards, which can be used for 3D acceleration:
Combination 2D/3D cards. These are ordinary graphics cards, which have been equipped with extra 3D power.
The pure 3D cards, which only work as accelerators. These cards require that there also is an ordinary (2D) graphics card in the PC.
Of course the pure 3D card yields the best acceleration, but there are also good combination cards on the market.
