Pc crash

So when i installed nfs payback i got into the loading screen and the first thing that happend when i pressed enter was that my entire system shuts down.

So i tried to get into the game again and it let me play for a little bit and then it shuts off my system agian.

I tried stability test on aida64 and had no problems and its only nfs payback were my pc shuts off.

Specs 

Gigabyte aorus 1080 ti only factory overclocked tried underclocking but that didnt help

i7-6700k not overclocked

Corsair cx750m psu

Msi z170a mpower

Corsair vengence 16 gb 3000mhz only running 2133 mhz

 I have the newest drivers there is.

So when i tried the aida64 my temps on the cpu: 63 max and the gpu: 62 max. So its not overheating.

So why does it only shut down the pc when i play nfs payback?
