Building a computer yourself instead of buying one ready-made from a store, will let you create the machine that you want. It will allow you to choose the best combination of hardware to achieve the kind of performance you require from your computer.
- Choose and prepare the necessary hardware and components. Decide on what type of hardware and components you want for your computer, like motherboard, video card, sound card and DVD ROM. Make sure all the parts are compatible with each other. Once you’ve decided on all the parts, go the store with a list and purchase the items.
- Prepare the PC case. There are different types of PC cases but they are all basically standard. Attach the power supply to the case and make sure it is screwed in tightly. Attach a fan to the PC case; this will help cool your components. Depending on the type of PC case it may have metal plates covering the drive bay. Take the metal plates off carefully.
- Prepare the motherboard. Carefully align the microprocessor chip on the motherboard. A mark on one corner will indicate how the processor will sit on the motherboard. Once aligned you can let it fall into place and secure it with the lever. To place the heat sink on the processor, apply the heat sink grease or sticker then fasten into place with a bracket. Some heat sinks may require a different procedure so just follow the manual that came with it. Place the RAM in the slot designated for RAM on the motherboard. Install the video card, sound card, LAN card and other components in the slots on the motherboard.
- Install the motherboard in the case. Place the faceplate in the case first; it should line up with the holders to secure it in place. Place the motherboard carefully in the case; use the spacers that came with it. Screw the motherboard in place. Screw the various cards, like the video card, to the case.
Connect the power supply to the motherboard using the connector from the power supply. Connect the fan to the power supply. Connect the power ON switch wire found on the case to the motherboard.
- Install the hard disk and DVD ROM. Place the hard disk into position on the case through the drive bay. Secure it to the case with screws. Slide the ROM device into position on the case. Now you need to connect the ROM and hard disk together with the cables it came with then connect it to the motherboard. Use the connectors from the power supply to connect to the hard disk and ROM.
- Attach monitor and other components. Close the case with the side panel. Attach the power cord to the back of the power supply. Attach the monitor to the back of the CPU with the cable. You can plug in the monitor’s power cable to the back of the power supply. Attach the keyboard and mouse to the CPU.
- Configure BIOS and install operating system. When you boot the computer for the first time it will run BIOS then it will have you configure the CMOS. Fix the time and date, and check if all the components have been detected. You may have to configure a few things like the video card and sound card at the CMOS area. Save your settings and exit. You will be asked where to boot from, since there is no operating system in your hard drive yet, place the operating system CD in the ROM drive and instruct the computer to boot from the ROM drive. Follow the instructions to install the operating system and wait for it to finish installing. Once it is done it will automatically restart.
- Install your programs and configure your operating system settings. Install the programs you intend to use on your computer and configure the settings on the operating system interface like the settings for the display, audio, and internet connection.
It will be cheaper to build your own computer and you will be getting the exact hardware on the computer you require for it to perform the way you want it to.
