Computer Crashing on a daily basis

[pmoss60]

Hello

My computer has been crashing for a long time on a daily basis when playing any game. I replaced my graphics card, RAM, power supply, computer case, and monitored temperatures so I'm pretty sure it is not any of those causing the crashes. I've scanned my computer for viruses and found none multiple times. I reinstalled my OS but I'm not sure if I did it correct (first time doing it). Help with this frustrating issue is appreciated.

Thanks!

Specs:

OS: Windows XP home edition
NVIDIA GeForce GTX 480
Intel(R) Core(TM)2 Duo
4GB RAM
ASUS P5N-D motherboard

I assume you also installed SP3, all other XP updates, and the latest video driver from Nvidia?

Have you checked to make sure the CPU is not overheating?
