One possible problem may be the BIOS is set incorrectly for your setup. Look up the BIOS resetting procedure, usually setting a jumper or pressing a button for a few seconds. Cause this happened to my boss's son's computer, nothing would work, no beep, blank screen, and non responsive. So he bought a new motherboard and CPU and I switched them for him and took the bad parts home with me. Just for the fun of it, I reset the BIOS and it came right on. So now I'm the owner of the "bad" parts. ;-)
The only thing that gets me mad about the situation is that the son whined enough while his computer was down, that he got himself a $3,000 Alienware laptop. And now that his fixed desktop just sits in the corner with a Radeon 9800XT in it going to waste. :boohoo:
