BSOD playing demanding games, Error Code 0x00000116

Greetings,

So for a good while these BSOD's dissapeared but are back and now am at ends wit.
About a year ago I had constant BSOD's with any games I played though Warthunder and Warframe gave the biggest guarantee for this , So I figured after reviewing my problem and the info I could find to swap my graphics card so switched from a 680 to 780GTX and that seemed to alleviate the symptoms but as only mere weeks they returned and I decided to visit the store where I buy my gear.

They checked my whole system ran standard benchmarks but also the Warthunder benchmark but it did not BSOD for them at any point, which was not helpful but what was noticed was the CPU heat so we replaced the cooling. To make things more odd though the BSOD's where caused by dxgkrnl.sys, dxgmms1.sys and nvlddmkm.sys they dissapeared for nearly 8 months after replacing the cooling.

So now I am again unable to play certain games as they almost instantly BSOD.
Monitoring my system on my second screen no oddities occurred before the BSOD (HWmonitor) even the temperatures never hit above 65C.
I tried turning off various services, ran CCleaner, Reinstalled Windows, ran Checkdisk, turned off all booting non essential software, I am probably forgetting something but I just can't figure this out.
I think it could be the motherboard or RAM but I most of all suspect a bad power network (seeing as we have light bulbs burn out in mere days).

Now my question is what do you guys think it could be and how can I figure this out with utmost accuracy?

I attached the zip with all requested information but let me know if more is needed.

Thank you in advance for any help.

Sincerely

(Other games like GTA on near highest settings won't cause BSOD's or SWTOR, GalCiv3 neither nor smite nor Elite Dangerous)
