I'm having a problem with a PC freezing on a fairly regular basis and it seems to be more frequent. I think the graphics card is the culprit but thought I would get some other opinions. The symptom is a frozen screen with some pixelation, meaning the image is still seen but a large number of pixels turn various colors and the machine is unresponsive. It seems to be random (every day or so at this point) but happens a lot more often when the Netflix MCE plugin is used, almost every time now. I have Win7 64 bit installed but the behavior was present on a previous Vista 32 bit install. I have swapped the motherboard out(for another reason) and the behavior is present on both boards. I have run MEMtest for several hours with no errors. The case seems cool(and the temps are in range when I check) and the top case door is actually not on as it's in a console that hides the fact that it's missing, although the behavior was also present before this setup. I've tried several but not all available drivers. I have had a previous problem with a 9650m that required a driver lower than 185 that showed similar behavior on my laptop. Finally, I have a 500 Watt power supply so I don't think that would be the issue. This card has been sent back once before for causing the system to fail at boot. So it seems obvious to me but I thought I would post just in case. Maybe someone has seen this behavior. I've searched but no one seem to describe it specifically. I also haven't spent any money on the problem so I want to be as confident as possible. Thanks.
