Fishing for ideas

I unplugged the on button from the motherboard and plugged it back in. Now the computer freezes every 1-4 hours of use. Any idea what the cause might be or anything I can check for. The computer isn't mine so I feel really bad and need to fix this if I can.

Specs? You don't give much info. Was it fine before you messed with the on button? What are the temps? Is the machine OCed?
