How to Build Your Own Computer

This page is intended to give you a general idea about building your own computer. It is not a detailed step by step guide. There are plenty of those elsewhere on the net. My intention here was to introduce you to the parts required and give you a basic, simplified idea of what makes up a computer.

There are obviously a plethora of possible computer configurations and hardware that you could put into a new computer. I have selected the basic components required for a general purpose home or small office PC. The Parts I have selected below are from Umart and the prices are in Australia dollars ( As of 26 Dec 2018).

1. These are the parts that I have selected in order of importance.

Prices are in Australian Dollars from UMART.

2. These are the basic steps for assembling a computer:

     (1) Mount the Processor, Heat Sink and Fan to the Motherboard and connect the fan power cable.

     (2) Install the Memory (RAM)

    (3) Prepare the case.  Install the power supply and make sure the mounting studs match the motherboard mounting holes.

     (4) Mount the Motherboard to the case and connect the power supply cables.

     (5) Connect the front panel cables to the motherboard.

     (6) Install the Hard Drive and Optical Drive.  Connect their power and data cables.

3. The following is a more detailed guide to assembling the Motherboard:

     (1) Attach your anti-static wrist device and make sure it has a good earth connection.  Static electricity in your body or clothing will damage the components.

     (2) Unpack the Motherboard, Processor, Heat sink, Fan, and RAM and set them on your work bench on top of their anti-static protection. Make sure you do not touch the contacts.

     (3) Installing the CPU: This is the most critical step. You have to be very careful installing the CPU. These steps were copied directly from the Motherboard Manual.

6. Turn the PC on and watch the screen,  Press the F2 key or the Del key to enter the BIOS setup. Configure the BIOS to boot off of the Optical Drive first and Hard Drive second.  Insert the Windows 7 CD, save the BIOS settings and exit. When the computer reboots it will boot off of the Windows 7 disk. Follow the prompts to install the operating system.
