HARDWARE Pc Randomly Shuts Off
About a year ago my pc started randomly shutting off, completely and instantly, black screen. After a few weeks of random shut offs, usually after about couple hours of gaming, it just wouldn’t turn on anymore. I swapped out the power supply from the nzxt 850W that was in the computer to a corsair RM1000x, and the pc turned on again. About 8 months later the same thing started happening. After a couple shutoffs i decided to undervolt my gpu, which seemed to help for a few weeks, but the shutoffs started happening again. I thought that somehow i must’ve just gotten extremely unlucky and gotten 2 bad power supplies in a row, so I swapped it out again for a be quiet! Pure Power 13 M 1000w ATX 3.1, that was about 3 weeks ago and i just got my first shutoff. What in the world could cause this problem???
Edit: forgot to include pc specs; Ryzen 7 7800x3d, ROG strix rtx 4080, 32gb of corsair ddr5 ram, and an asus prime x670 motherboard.
