I had the same crash issue with my PC. I just discovered my NVIDIA card was not ramping up the fan speed on the GPU block. This was causing my system to crash.
I have an Asus GTX660-TI video card. Asus has a tweak program that allows you to monitor and overclock the card. The fan was on auto but never seemed to go higher than 10%. I figured I would put it at 100% speed and that cured my problem. I have been able to play straight for several hours now without issue. I also noticed using the video card monitor, that my card is running at 100% during game play!
At 100% fan speed my Video GPU temp holds at 51C. Give it a try. Holding my video GPU temp down cured my crash problems.
i have tried this also, as i was not convinced that it was giving the right speed for what the game was pushing it to do.
However, nope still the crashes
even with all the tweets and changes to drivers etc.
I have given up and now playing it on my wife's a lot older 9k series GFX card. ☹️
