Desktop Assemble / Inside a Desk

Assembling a desktop is not at all a hard task. It’s the way people start of their expertise on the field of computer hardware and which might later on lead to computer software .

It is indeed very simple to dissemble – assemble a desktop computer. The image below shows a motherboard and its components.

Locate the latch as show in the image, raise the brown lever on the socket and put in the processor gently; make sure the processor is inserted correctly and that that pins on the processor go into the motherboard perfectly. However DO NOT force it in; slid it in gently. If you are having a hard time putting it in see whether the processor is turned to the right angle if the problem persists it is most likely your motherboard does not support your processor. After the processor is inserted close the brown lever which will secure the processor in place

You will have a Heatsink and a Fan with you. Remove the plastic cover on the fan,- place the heat sink gently on the processor and the Fan above it, make sure the Fan clicks onto the Heatsink and the motherboard. After that is complete plug in the fan to the motherboard. Do not worry when doing this, the plug will only fit into one socket so go a head, normally this is located at the edge of the motherboard.
Also ensure your Fan is set to the correct speed to cool down your CPU If not the CPU will over heat and will cause serious damage to your processor which will cause system failure. (Do not worry if the processor is heating up the motherboard will send out a beeping noise and will shut the PC down to avoid damage).

CPU fan is connected as shown in the image

CPU

If you are installing a motherboard I highly advice you to install your processor onto your motherboard before installing the motherboard into your desktop case.

Locate the processor socket on your motherboard.

I am installing an Intel PIII processor on a socket 370 as shown on the image on the left. The installation would be slightly different if you have a different processor i.e. PIII CPU, Celeron CPU/370; P4 CPU/478 socket; AMD Anthon CPU/Socket A etc.

Graphics Card

Most modern graphics cards are AGP based and connects to the AGP bus of the motherboard. It looks like the following image. The brown slot is where you connect your AGP graphics card. The AGP slot is located at the top of the slots, This is where the Graphics card goes in.

Motherboard Assemble

First take the Desktop Case and keep it on a table in a way that your facing it, take out the cover of your case for you to access the inside. Take the screws and mounting screws provided with the case. It is important that you use the motherboard mounting screws to avoid motherboard from short-circuiting. This will cause the computer to not start up, it will also damage your hardware.

Screw your motherboard mounting screws into the casing, after this is complete place the motherboard gently on the mounting screws. Make sure your ATX devices on the motherboard such as PS/2 and parallel port are facing towards ATX back plate cut out. Gently push your motherboard towards the cut out, every devices should fit easily into its corresponding cut out,

Ensure the motherboard is in place, your motherboard should align with the screw holes on your case. Place your screws that came with the case into the appropriate holes and gently screw it on using a screw driver.

Your ATX case should come with the power supply it and should already be mounted to the case.
since the motherboard is now securely mounted to the case. You can now place the ATX power connector to the motherboard as shown in the image below.

Place the ATX power connector on top of the power socket on the motherboard. Push down the power connector and it should clip onto the socket. If you try to fit the power connector the wrong way round, it won't fit, it will only fit one way. So, if the power connector does not go in, it should go in the other way round.
