Hi, I have been having this problem for some time now. i though it was a hardware problem at first and replaced the psu and chipset heatsink but its still happening. The pc just freezes at times, usually when im not bloody around. Thing is, it will be fine if i leave it playing music or in a game. I have checked eventvwr.msc and cant find any entries. Any ideas ? im stumpted. If ye need to look at any logs just ask.
