How To Build Your Own Personal Computer



Adding the Main Components.

This section shows the connection of the power unit, installation of the Hard Disk Drive (HDD), the floppy drive (FDD), Memory, Graphics cards (Both AGP and PCI) and modems etc.

First, we connect the case power switch, reset and HDD LED to the MB

 

You have a bundle of wires leading from the front end inside the case.

Figure 4.1 shows the general configuration of connectors but check your MB manual to find out exactly where it is and the configuration you must use. It varies between MB's. There is also a speaker connector that also simply plugs in.

It is important that it is done properly or nothing will happen when you switch your new PC on. Get the power-on switch right at least!

Here is how a particular board is set up; the row of pins are circled.

I ALWAYS install the HDD, floppy drive and CD ROM/DVD/CDRW after the MB.

If you start by installing PCI and AGP or memory modules, you will have to remove them in order to put the HDD etc in the case. I know from experience!

You will notice the cages at the front on the inside of the case. The CD units go in the large ones at the top, then the HDD and the FDD go in the smaller ones that are lower down.

It’s easy to see where to put the floppy drive; it must line up with the external access point so you can put your disks in. Anywhere on the same part of the cage that you can get the mounting screws to line up will do for the HDD.

Small brackets on the inside of the cage let you simply slide both units in to the case.

Important: Make sure the power connector on the HDD is facing outward, towards you. The orientation for the FDD is simple; the button that ejects the disk must line up with the external button of the case. There’s no guesswork there.

There are many makes and models of both HDD and FDD, with varying prices, but they all serve the same function. For your FDD, it's an easy choice about which model to buy, get one that suits your budget and save money, if you can, for the items to come.

Installing the HDD

The HDD is where your programs, including the vital operating system, will reside.

You can buy HDD's with a capacity from 20GB up to a massive 200GB.

Your choice depends on what you use your PC for. A 60 - 80GB HDD would serve most needs but you need to consider a larger HDD if you will be, for example, editing videos.

The IDE cable has a notch in the middle so you can't really go wrong connecting it. The power cable can only go in one way as one side is beveled.

If you have any doubt, just remember red to red for IDE and power cables.

The IDE cable has a red line that runs the full length of the cable and should face the red wire on the power cable.

Installing the floppy

The floppy drive has to be inserted from the inside. See HDD installation above.

Installing a CD/DVD/CDRW

Remove one of the front panels from your case - they simply push OUT from the inside.

 A new unit will have mounting screws for the inside cage and an audio wire to connect your CD to the onboard sound connector or to your sound card.

Look at the back of the unit to see where this wire connector goes: R marks where the red wire should be.

There is another row of pins with a little jumper. You will see (M) Master and (S) slave - this is important if you are putting more than one unit in the system i.e. a DVD and a CDRW.

I always mount the DVD on top and the CDRW below, then set the DVD to master and the CDRW to slave. This lets the Bios recognize that you have 2 units (more on that later).

You will see a long double-row of pins next to that. This is your IDE connection and next to that is the power connector.

Let's assume that you are just installing 1 unit for now.

The unit itself, whether it is a DVD, CDROM or DVD writer, is a standard size. Fit them as shown below.

I connect the audio wire and the IDE cable to the back of the CD/DVD etc. before I push the unit into place. It makes life a lot simpler.

The IDE cable has a notch in the middle so you should not go wrong connecting it. The power cable can only go in one way as one side is beveled. If in doubt, just remember red to red for IDE and power cables.

The IDE cable has a red line that runs the full length of the cable and should be facing the red wire on the power cable.

The IDE cable attaches the CD, HDD and FDD to the MB. It is responsible for data transfer and generally comes as part of the MB package, folded like the one below.

The Memory – RAM

The standard memory for most Pentium and AMD boards is either DDR or

SDRAM. The DDR module has one notch and the SDRAM has 2.

Some MB’s only have sockets for one type. Others have sockets for both but you can only use one type in any machine at one time due to frequency and timing differences.

DDR RAM is reputed to be the best choice; it is faster in benchmark tests.

Your system will not function without some kind of RAM installed and the more, the better.

What does RAM do?

It is short-term memory (your HDD is your long-term memory). Any data written to Ram disappears when the power is turned off. If you need to keep some information, save it to your HDD.

More RAM will allow your applications etc. to load more quickly. It will also increase the multitasking capabilities of your PC.

I recommend at least 256MB DDR or SDRAM MINIMUM and, preferably,

512MB. The price of components are dropping so memory is becoming more affordable.

With your anti-static gear in place, you are ready to install the RAM!

This is an illustration of a DDR RAM module and its socket on the MB

Unlock the socket latches by pushing them outward; align the memory module on the socket so that the notches match.

Firmly insert the memory module into the socket until the retaining clips snap into place and the module is properly seated.

With the memory in place, start to install extra options. Many modern MB’s are made for simplicity and ease of installation. The MB that is illustrated on this site has on-board audio, on-board graphics and even an on-board modem.

These inbuilt features may not meet your requirements, so we will now introduce the installation of AGP and PCI based cards.

Don’t worry about the terminology - it's all in the jargon buster.
