Monitors crashing to black screen while gaming

[Ddave]

Issue: When playing games, it will crash to a black screen and will require a force-shutdown the PC just to be responsive again. Alt+Tab, Alt+F4, and Ctrl+Alt+del does not work.

 

Initially I thought this might be an issue related with GPU temps. So I enabled MSI afterburner's OSD and true enough, it reaches up to 90c even at 100% fan speed. I replaced the thermal paste on my GPU (old paste was dried up), but reused the thermal pads because I do not have any replacement on hand (more on this later). I did a few tests and the max temperature it got was around 70c. After playing for a while I still encountered the issue even at less than 60c.

I thought maybe reusing the thermal pads caused the VRMs to overheat or something so I connected a monitor to my motherboard and had it display hwinfo while I played. Issue occurred while playing This war of mine and even my second monitor froze. From what my noob eyes see the temperatures seem to be fine.

 

Below are the GPU temps from hwinfo:

 

 

I'm not sure if this is even an issue with my GPU. Any ideas on what's causing this?

Additional detail:

GPU memory Errors increase whenever I start a game. Fired up XCOM and in the main menu it's increasing at around 1-3 errors per second. In the picture above it shows 9.5 billion errors.

Valley benchmark did not cause the errors to increase. It does, just at a slower rate.

Hey! Your gpu might be outdated, this has happened to me too, try to remember when did you build/buy ur pc. Also did you get a black and white screen when booting up after the black screen?
