Crash every hour

So I seem to be crashing every hour consistently. First day, I crashed once, second day crashed 3 times. Since yesterday, I’ve been crashing every hour.

I’m not crashing to desktop, nor a BOD. My comp straight restarts. I’ve checked temps on both GPU and CPU (I have them logging), I’ve updated drivers. This is the only game I have issues with consistently. This is constantly causing my save to be corrupted. Thankfully, someone else on the forums had a fix that worked for me (they had two copies of my save. One with a .sav, the other with a .temp. I just switched the file extension, and my save was fixed)

I have a i7 8700k and a 1080ti. Not really sure what the issue is.
