Question Crashes when gaming

[swissc]

I used to play a lot of War Thunder but then it started constantly crashing on me. The games just freezes completely and I have to hold the power button to reset it. As I never had a problem with Battlefield 1 I assumed it was a problem with WT and have been too busy with work to investigate further. Due to the lock-down I downloaded Call of Duty: Modern Warfare, now I get the same problem. I have checked with MSI afterburner and temps are <60 degrees and GPU/CPU are not maxing out. GPU drivers are up to date and McAfee is not picking anything up. I ran MemTest86 and all was fine. Any ideas of where to go next?

I tried it again today with Far Cry 5 and exactly the same thing. FYI, all the games are stored on the larger Seagate drive

do you have any bsod error code also i would test psu with occt and the gpu with gpu-z rendering option .

OCCT: occt and OCCT:Linpack both ran without errors for 1:30 and 3h respectively.
OCCT: 3D ran for 530seconds then froze with 0 error count. As with gaming the system froze and I had to hold the power to reboot. I am continuing with the other tests.

Very occasionally it gave an bsod but I would say 99% of the time it was just a freeze without.

OCCT: Memtest also ran for over 1h without errors, but OCCT: Power also froze the system within 5mins just like the 3d test. GPU=Z render test ran without a single issue.
