Game crashes computer on new campaign

I bought WFTO on launch and played it without any major issues, however I decided to wait until the game had been patched to do a proper playthrough. After the most recent update I decided to try again, I can launch the game just fine, navigate the menus and all that. I reset my campaign progress and then started the first mission. The cutscene works just fine, the game starts to load, and then my entire computer shuts off.

I have verified the integrity of the cache and while some files were initially missing, this continued to occur after they were re-acquired. This problem is exclusive to WFTO as I have played a wide range of games for hours on end over the past months (Overwatch, nearly all the Call of Duty's, Ryse: Son of Rome, GTA V, CIV V etc.) with no issues. The only other game that experienced similar symptoms was Enemy Front, which I refunded after it caused these hard crashes.

Any help would be greatly appreciated. Specs:

Windows 10 Pro 64bit

16 GB of DDR3 RAM

GTX 980ti (slight OC)

Intel i5 3570k @ 4.2 ghz

WFTO running on a 7200 rpm HDD

Nvidia driver 368.69 and it's predecessor (I have tried to play the game a few times over the course of the last month)
