Do yourself a favor i sense your trying to learn about computers.
The best way to teach yourself is to study motherboard manuals/ books etc...
They have MOST but not all the info you desire . Theres ALOT of information on the web about how to work on or repair computers . You need to study that information your local librairy will have an abundent source of info as well. Once you get a basic understaning on how the technology works you'll be better adept to present a question that we can understand and lend a helping hand .
Computers are alot of fun so dont get discouraged and keep studying about them ... Good luck
