I had this issue in the past with other games and here is what you may try to do.
Go to Windows Event Viewer: start>search>type:event viewer>run as admin>expand the "windows logs" menu>application> and look for the most recent error, (or fatal error), message in the list or if you know the exact time of the error also use the time period in which your PC crash.
In most cases the error is related as an "kernel power failure" or "kernel power loss" ... something like that.
In this case go to your BIOS menu and save your current OC profile and reset BIOS to default settings.
The game cause some massive hardware resources while loading and for this reason your OC profile can "punch" your components with big power demands that may not be set in the perfect way by you.
If your PC won't restart with stock BIOS settings you may consider to try small power adjustments in your OC profile (+/-) and I would try to decrease voltages in the first instance.
Also keep in mind any OC will cause an shorten life to any electronics... sooner or later.
I hope you will find your way back to the game.
