Freezes/BSODs, with artifacts
My fairly new pc (2-3 months) has started to have freezes/blue screens, sometimes with artifacts visible.
My graphics card is a Sapphire 4870 (1gb GDDR5)
I think there might be a problem with the temperature sensor on the graphics card, because even while playing Crysis at near-max settings, it only reports 50-55C. I've read that other people using this card see temps up to 80C with no problems, so something seems wrong there. My original thought was that the card was overheating and the temperature sensor wasnt detecting correctly, and therefore not automatically increasing the fan speed, causing it to freeze. However, if that was the case, manually setting the fan speed should have stopped the freezes, but it didnt. I have it running at 50% constantly, even when not gaming, and it still freezes sometimes (always when watching videos or playing games).
Any input would be very helpful. I'm not overclocking anything. The card, processor, and RAM are all running at default speeds.
