PC freezing problem

[htphm42]

Okay, here's the deal. PC loads up and works fine, but after 20min or so of use or idling, it would just freeze. You could still move the mouse, but be unable to click on anything. I ruled out the PSU and HDD. It's a clean install of xp too. I'm thinking it might be mobo or ram related. If anyone has some expertise, that would be really great. Thanks.

id say run memtest to check the ram.. boot into safe mode to see if its driver related or windows related as well since the majority of drivers like video will not load in safe mode.. check your temps as well make sure the system isnt overheating though i doubt thats the problem.. theres a troubleshooting sticky thread at the top of this forum section you might want to check that out see if any of that helps you..
