I have had this computer for 2 years and recently it had been black screening for me (4-5 months or so), this black screening only occurs during gaming such as OW2, CS2, BF5. It crashes in two different ways, one is where the screen immediately blackens but the computer is still running and second is where the screen blackens and the systems restarts.

I have raised this question before to a windows forum asking for help, and the minidump files pointed in the direction of the GPU. So I thought this might be a GPU issue and decided to run Furmark benchmark test on it, however everything was perfectly fine. But I still decided to warranty the GPU as I suspected overheating of the memory at 105 degrees. Gpu was sent for testing for furmark and even sent to Taiwan for further testing but no problems were found.

As the Gpu was being sent to Taiwan, i used my onboard Cpu graphics to run games and didn't black screen once. (was on low settings)

I am really confused as to what the issue is with my computer, please help.

Other test/rectifying solutions I have tried:
Memtest86
Swapping out SSDs
rebuilding my system

These are my mini dump files and HWINFO data as I crashed.
