Building a computer is quite simple. Here is a quick overview of what needs to be done.

1. To build a computer, you first start with the case. If your case came with a power supply you should be covered, but if it did not, no big deal. Simply install the power supply.

2. Next take the motherboard and set in the CPU processor chip. There is usually some sort of locking mechanism to make sure the CPU doesn't fall out.

3. Next install the heat sink / fan which keeps the processor cool.

4. Next, install the ram chips. Make sure they lock securely.

5. Next screw the motherboard into the case. Connect the power clip from the power supply. Do not plug in the power supply to the wall yet!

6. Install the video card.

7. Screw in the hard drive

8. Screw in the cd-rom

9. Connect the ATA or SATA cable to the hard drive and cd-rom. Connect to the power to your hard drive and cd rom.

This is basically it. On average it takes me about 15 minutes to do this. I took my time the first time through and it maybe took an hour. There are a few things you need to know for each step which I will cover in more depth, but this the basic idea.
