Computer randomly restarts while playing certain games

This happens most often while playing grim dawn, but its happened very rarely on minecraft, sekiro, and titan quest. Sometimes it happens immediately, sometimes I can play for hours with no problems. Temperatures are fine, CPU never going above 60 and GPU
never above 50. Screen suddenly goes black and then my computer starts loading up again automatically.

Specs:

• CPU: Ryzen 5 3600
• GPU: EVGA GTX 1080
• RAM: 2x8gb G.SKILL Ripvaws V 2400mhz
• Motherboard: MSI MPG x570 Gaming Edge Wifi
• PSU: Corsair CX750M

Things I've tried:

• Reinstalled game
• Reinstalled/updated graphics drivers
• Changed fan curves
• sfc /scannow
• Windows updates
• BIOS updates
• enabled/disabled XMP
• enabled/disabled virtualization
• reseated cables
• reseated ram
• ran memtest86 with no errors
• tried different outlet with and without surge protector

It has never restarted while idle, and hasn't restarted while playing the vast majority of my games, most being significantly more demanding. I had the problem initially on minecraft, but then it suddenly stopped and I've been able to play it fine with no
issues up until now. Still restarting in the other games. I remember this happening on grim dawn one or two years ago, but I stopped playing and forgot about the problem until recently when I tried playing again. It's never restarted during any CPU or GPU
stress tests. No relevant information in the event viewer as far as I can tell, only the generic kernel power 41. I have no idea what else to try, and I'd appreciate any help I can get.

 

PC Randomly restarting when i am playing games

My computer randomly restarts when gaming, i dont get any BSOD, its just a black screen then it reboots. it does not restart when i am not gaming, it only happens when i am playing games. I don't know what is causing this, can someone please help?

 

Computer again randomly restarts while playing certain games

I asked here a while ago about the same issue. I disabled all the startup programs
and services and that appeared to work up until now where its suddenly happening again. Everything is still disabled and I haven't changed anything else since then. Anything else I can try?
