Strange crashing in Games/problem with monitoring software too!

[SinisterDev85]

Ive been experiencing this strange crash recently. Trying to track down the culprit. I havent been playing many games, but thus far Ive experienced the same type of crash while playing Diablo 3 and Fallout 4. Suddenly my screen will go blank, followed by loss of signal. The only way to get it working again is to unplug my HDMI from the video card and plug it back in. Then the signal gets restored. If its Diablo, I get a problem with"D3D" error and it asks me to retry. Sometimes I can get the game working again after that.
With Fallout 4, the game simply crashes to desktop. That's where the next problem comes in. After this type of crash , I cannot open Nvidia Control panel, and any monitoring software I was using at the time, say MSI Afterburner or EVGA Precision tool all show Temp.,Gpu and Cpu at 0. Seems to happen in any monitoring software that was running before the crash. Only resetting the PC seems to resolve that issue.

Any ideas? I really hope this isnt a problem with my video card. Its fairly new ...

I get the same thing with sfc /scannow, it found corrupted files but could not repair them. I contacted Microsoft and they said because I did the windows 7 upgrade it has something to do with the leftover windows 7 files and not to worry.

My pc runs fine otherwise.
