Building computers is easy once you get the hang of it. I assembled my first one around the year 2004. I had already watched the video cassette recorder tape of how to do it. Thus, I was certified that same year.
First of all, you have to buy and gather all of your hardware components, which start with the motherboard. All internal parts must be compatible with the motherboard. They includes processor, memory, video card, case, which all of the internals go into. Example of drives include serial advance technology attachment or SATA or integrated drive electronics or IDE. You need the power supply, and finally all cabling and cooling fans. These are just the basic parts you need to have a working computer.
Open up the case, and there should be a tray that holds the motherboard. Use proper offset screws to prevent shorting out with metal on metal between main board and tray. While, the tray is still out, it might be a good time to install processor, processor cooler, and memory.
Building Computers Is Not Difficult
Some processors come with stock fan and heatsink having a thermal pad for easy installation. If you buy a separate cooling device for your central processing unit, CPU, or processor, you will need thermal paste or compound to apply and cover between core and heatsink surface.
Depending on position, before reinserting motherboard tray back into case, you might want to secure the drives into the bays. Of course, you also want the power supply in either first or last depending on the size of your case.
Put your video card in thus making sure there is room for it to fit and that it is secure. The last part is making sure all of the power and data cables are connected and everything is seated snugly within the case. Beforehand, you can also make dry or bench runs after installing each component from processor, memory, drives, cards, and so on.
Then you connect basic external like monitor, mouse, and keyboard then start and hope it boots into basic input output system or BIOS, where you can change boot order, such as DVD drive first for installing the operating system. You can also overclock the processor here.
After you get the operating system installed, you can now add other software and/or devices such as printers, webcams, and so on.
You have just completed your first computer assembly. As a resource, Wiki tells you How to Build a Computer.
