Just recently my GPU started to heat up a lot. I discovered this after all my games crashed within 10 minutes of playing them. My computer is quite new, so I'm surprised, and I don't really see an obvious reason for this to have happened. I know that my fans are working, because I've used EVGA Precision to increase fan speed, and I definitely hear the increase in fan noise. However, this did not stop the crashing. So I'm beginning to think my graphics card is faulty, or pehaps there may be some other reason. Here's my specs: OS: Windows 7 Home Premium 64-bit Processor: Intel(R) Core(TM) 2 Quad CPU Q4800 @2.66GHz (4 CPUS) ~2.7GHz Memory: 8GB RAM DirectX: DirectX 11 Video Card: NVIDIA GeForce GT 220 My GPU temperature at the moment is 72 C, and the rest of the temperatures seem normal(in the 30's to low 40's). I haven't opened up my computer case to see if indeed it is too dusty. I'm a bit suspicious about this beign the reason since my computer is relatively new. So I'm guessing my card is faulty, but you never now. What should I do?
