I also get these complete system crashes with dx9 and dx11. I'll log in and sometimes be smooth for a couple hours other times just 10-15 minutes and game sends my comp into a bsod with noise. Only a hard system restart will get my system back up and running. Can't find any issue with my comp and I can play plenty of other intensive games without an issue and no issue when I run a maxed out system benchmark. I'm running an intel 4690, gtx 970, and 16gigs of high speed gamer ram.

This is getting really annoying as I just returned to the game where my old system before upgrade would play at max settings without a hitch. 3 times in a row now crashed trying to do the first machinist duty.
