So when I play Skyrim (SE), Minecraft, or Arma 3 (not too sure about Arma 3, as it only happened once.) My computer just totally shuts off no bsod then turns right back on as if nothing happened. I am at my wits end. I can play more demanding titles like BF1, GTA V, and Total War: Warhammer for HOURS. But when I load up Minecraft or Skyrim my PC just shuts off. It is unbelievably annoying. I know it's not my PSU because I can play more demanding games for hours on end with zero issues. This has been happening for about 2 months... And all I want to do is play some Skyrim.
--------------------------------------------------------------------------------------------------------------------------
What I have tried so far:

Switch ram slots

Reinstalled Windows 10 (multiple times, STILL HAPPENS!!!!)

Made sure my PSU fans spins (I had this problem before... a cord was stuck in the PSU fan so it didn't spin and it overheated.)

Stress tested CPU, System Memory, FPU, and Cache with AIDA 64, and at the same time stress tested GPU with Furmark at 1080p 8x MSAA and no crashes at all.

Updated Bios.
--------------------------------------------------------------------------------------------------------------------------
My Temperatures are all normal, GPU never exceeds 65 C and CPU never exceeds 20 C when playing Skyrim, but when stress testing GPU never exceeds 65 C and CPU never exceeds 70 C.
--------------------------------------------------------------------------------------------------------------------------
My Specs:
CPU: 6700k @4.7Ghz
RAM: 16GB Crucial Ballistix 2400
GPU: ASUS Strix 970
Motherboard: ASUS Z170 Pro (non gaming version)
PSU: Corsair HX750 (Plenty O' Power and gold rating)
--------------------------------------------------------------------------------------------------------------------------
Overclocks are rock solid stable, GPU is oc'd to 1500mhz, and VRAM is +100mhz so whatever that is, too lazy to check lol. CPU is totally fine and has been overclocked it's whole life and has had no problems at all.

Please Help.
Thanks In Advance!
