Hello Ill make this quick. My GeForce 6600GT AGP has suddenly started overheating. When its idling it sits at around 63 degrees, but quickly rises to 80 - 90 while gaming and artifacts begin to appear. It wasnt doing this yesterday. It only just started happening today. What could be causing all this overheating? My room isnt at all that warm and my case has good ventilation. Also, the GPU fan is spinning. Thanks, Nissanman. edit: i was using both Everest and SpeedFan for monitoring the temps.
