From last month my Asus Radeon HD 4850 has been having problems. At first it was a few artifacts, but now it is beginning to BSOD and produce graphics like this in Mirror's Edge:
The temperature isn't too high, and the fans spin smoothly without much dust. I've run memtest and the RAM seems to be fine. Latest drivers from Asus and ATI don't help, and downgrading doesn't do anything either.
I am not sure if the power supply or the video card is going, I put in an old Geforce 8600GT and it works, but it is so much slower than what I was used to with the 4850. I do not have an extra power supply to replace my old one with; is there another way to see if the power supply or the GPU is at fault?
