The #1 cause of PC's breaking is the power supply, followed closely by the USB hubs blowing out.
If you have access to another power supply, try swapping it out.
I'd try giving you more help, but I don't have a clue what you are running or where it is failing.
Vista/XP?
Can you see the BIOS screen?
If So, do you get to the Windows Logo?
Have you tried booting in Safe Mode?
