Not too great with computer hardware, just an FYI before I tell you about the problem. 
First off, specs?
Intel Pentium 4 2.0GHz
512MB RAM(Not sure what brand??)
GeForce4 Ti 4200
SB Audigy Audio
Don't know what kind of motherboard I have, but I'm sure it's an ASUS.
THE PROBLEM---
When I try to boot the computer, nothing happens. Everything is plugged in, everything is OK from what I can see. A little green light on the motherboard is on, when the computer is plugged into an outlet. This has happened to me before, I had a friend look at it and he installed a new motherboard, that seemed to fix it. I had this computer built for me about 2 years ago, and since my friend and I opened the case, fiddled around with it.. warrenty no longer applies.
