My problem is this: First off my computer never used to freeze until about 2 months ago. Then it started freezing in WoW commonly. The problem went away for about 2 weeks after fiddling with some bios settings (Like Taking off hyperthreading, changing AGP Aperture, etc etc)....I think it was just coincidence that it stopped freezing. As of today the computer is freezing even while browsing the net or using ventrilo or MIRC. I have speedfan running and the software from the nvidia drivers (91.31 I believe) and they are showing my card at about 60 degrees Celsius. I know right off the start you're going to say it's a heat issue but even with the case off and a powerful house fan blowing on the mobo the problem persists. I might be inclined to think its a PSU issue but again this problem did not occur previously, and now it does. I have a raidmax 420W power supply, which gives 13 amps on the +12V. So again, I think its *POSSIBLE* that it is a PSU issue but highly unlikely due to the fact that this DIDN"T happen until recently. My system: Asus P4P800SE motherboard 1gig Kingston RAM P4 3.2ghz Prescott XFX 6800GT Raidmax 420W PSU (13 amps on +12V). Thanks for your help!
