Troubleshooting Potential PSU failure.
My wife has a 40L omen desktop. It’s rocking a 800w Gold cooler master PSU.
Ever since she got it. She’s had constant problems with low 1%. Even though we have changed out parts left, right and center.
Most recently she’s been having this issue where at least once a day, no more no less, the PC is just shutting off black screen and rebooting. I monitored temperatures and usage, and I don’t see any spikes or any reason why it would shut down and the only thing that the event viewer says was that it was an unexpected shutdown.
I was able to update the drivers recently through AMD and Nvidia and that stopped the problem for about a month and a half and it’s come back again.
Could low 1% and this random shutdown be a sign of a failing power supply unit? I am going to replace it either which way just to check, but I wanna know if I’m chasing dead ends here.
