Problem description:
I've been having this issue sporadically for a while now, and tried a pile of fixes. Basically, with a pile of different games (Path of exile, shogun 2, Europa Universalis... mix of high-stress and low-stress games) I have had video driver crashes that never recover (event viewer has said they recovered, but screen remained black until I hard reset).

Attempted fixes:
I recently updated my BIOS, did a driver clean/reinstall, and similar, and now event viewer shows the error in the thread title - "application shogun2.exe has been blocked from accessing graphics hardware".

I have monitored heat, and as far as I can tell there are no heat issues. I have a relatively new, brand-name power supply with wattage in excess of what I should need. I have run memtest, prime95, and furmark to stress test things, and not had any failures or errors.

I have increased the TDR timeout to try to resolve this to no effect.

Recent changes:
The only change made to the system would be the video card and power supply, added at the same time. Previously, I had occasional video driver crashes, but they always recovered themselves. ATI drivers previously as well.

Windows 10 x64

System specs:

Have you tried using DDU and then installing the latest video drivers? http://www.wagnardmobile.com/?q=display-driver-uninstaller-ddu-

So you are on the latest motherboard BIOS?

What PSU exactly?

Yes, I have used DDU and then installed the latest drivers.

I am on the latest motherboard BIOS.

The PSU is an XFX Core System Builder 550w

I seem to have solved this (maybe? hopefully?) by re-running DDU and then letting windows install the WHQL certified drivers instead of the latest. No crashes since, but since this is so sporadic, hard to tell if that is a fix or just luck.

Thank you for the ideas.
