I've got a pretty solid setup with a 3090ti, Intel 13700k, Z690 Aorus Pro motherboard, 32GB of Kingston Fury Renegade DDR5 RAM, and a Corsair RM1000X power supply. My PC has been running fine for years, but today it just started rebooting out of nowhere after a few minutes, even when I'm not gaming—just browsing. I get a black screen with some numbers flashing on my motherboard, and then it kicks me back to the Windows login screen. I haven't changed any software or hardware lately, and I updated the BIOS about a year ago, which should've fixed previous issues with my CPU. So, I'm really confused and frustrated. What could be causing this?

It sounds like your power supply might be failing, but RAM issues could also be the culprit. If your motherboard has integrated graphics, try booting without the 3090ti to relieve some power demand. If it stops rebooting, it's likely the PSU. If the problem persists, consider testing with just one stick of RAM.
That seems to point towards the PSU for sure. Did you notice anything weird when you opened your PC? Sometimes dust buildup could cause issues too.
Have you checked if there were any recent Windows updates? Those can sometimes mess things up. It could also be worth taking a look at your PSU just in case. I've had weird crashes like that caused by updates before. Good luck!
I did try booting without the 3090ti, and it still rebooted. Sounds like the PSU is the main issue, huh?
