MSI R9 390X OC 8G - Crashes

Hello everyone!


I have an issue with my 7ish(?) year old MSI R9 390X OC 8G. Since I got her(new) she maybe once in a month decided to shut down my computer completely(Power Cutoff and I had to manually restart the PSU for the computer to turn on again). I didn't worry to much, cause I was googling the issue and other people had it as well, so I just thought it's the game. This happened only when I was playing Planetside 2, after a while I received from my friend his game-settings and that seemed to have fixed it.(Tuning down effects in general). So ruffly since 3 years I had no issues with her anymore.


Recently the issue came back up with new games.

For example [Game|Reason]

Deep Rock Galactic - When there are many explosions extremely close to me, my computer blackscreens and cuts the power.

Hell Let Loose - When there's artillery exploding and it's on my screen, my computer blackscreens and cuts the power.

Warthunder - When there's artillery exploding or a lot smoke spammed near me, my computer blackscreens and cuts the power.


The strange thing is, when I am working on my 3D Programs (Rendering complex scenes with GPU/CPU under high load) this does not happen. Even complex scenes in Substance Painter do not trigger this behaviour.

Even FurMark runs like butter for hours.


For some reason, this -power cutoff- only happens in games and ONLY if there are large scale explosions/smokes.


I am taking a lot of care of my computer parts, since it's nearly impossible for me to get new ones.

I am frequently cleaning my computer from dust and doing a complete deepclean every 12 months. (Disassembling everything(GPU/CPU) and adding new compound (MX-4)).

P.S.: These issues were in place, before I even did my first clean(Incase anyone thinks I messed up! I am really cautious with the cleaning etc.)


I checked the Event Viewer and the only thing it comes up with is Critical - Event 41 - Kernel Power. But that (for what I goggled) could be PSU CPU GPU MB etc etc and isn't to helpful.


I really hope some of you could help me.
