It was a hardware issue. My replacement is running perfectly.
For some reason, some games are causing my displays (2K primary + 4K secondary) to flicker, then reboot (if it crashes fast enough). If I’m lucky, I can stop the game, then it’ll stop doing that.
Some games I tried that’s causing it:
- Cyberpunk 2077
- Mass Effect Andromeda
- Life Is Strange: True Colors
the only game that didn’t cause that to happen is Mass Effect Legendary Edition.
Anybody here can assist me?

One other thing to note, I was using MESA from PPAs that are much newer than what ships with Ubuntu, but I recently just switched back to what came with Ubuntu or Pop!_OS (though they don’t seem to be different).
In addition, I was using this PPA when my issue ocurred. Same thing happened when I went back to what came on Ubuntu/Pop!_OS.
Reason why is because I was trying to fix an issue with my displays flickering at boot, and sometimes not working, which I fixed by plugging my desktop directly to the wall. When I tried to see what happens when I go back to the way it was, and no issues occurred at boot, I decided to stick with it.
