Can anyone recommend a good, free diagnostic utility (or 2) for checking NVIDIA video cards? I've tried AIDA64 but it seems to be more of a benchmarking kind of program. I'm looking for one which will, among other things, check the VRAM and let me know if it has a problem, along with any other components which might have failed or be failing. I'm not concerned about the performance per se, rather I just want to see if everything is working correctly. I'm suffering with the accursed "Display Driver NVIDIA Kernel Mode Driver Version xxx.xx Stopped Responding And Has Successfully Recovered" problem and I have to verify that there's nothing in the card itself which might be causing the thing to crash constantly. Thanks in advance...
