Hi everyone!

I have my nephew's PC that i need to repair. It freezes from time to time. It will boot and load Windows 7, after couple of hours or minutes it will freeze so i need to restart Windows.

I already reformated it and reinstall Windows 7. So the application side is ruled out. I also cleaned the dust from the mobo and RAM. Fans from CPU and chasis are running smooth. I'm thinking more on the hardware. Where do you think is the problem?

SPECS:
CPU: Intel Dual Core
RAM : 2 GIG DDR2
OS: Windows 7

Any help is greatly appreciated.
