I've had my PC for almost a year and it was running perfectly, but lately, it has been randomly shutting down during my gaming sessions over the past week. I've checked the temperatures of both my GPU and CPU, and they're all normal before the shutdowns. I also ran tests on my RAM with memtest86, and everything looked fine there too. My software is clear of any malware or corrupted files, and I've cleaned it of dust as well. I'm really stumped on what could be causing these shutdowns. Here are my specs for reference:
- Ryzen 5600 CPU
- RX 6650 XT GPU
- ROG B550 Gaming WiFi II motherboard
- Klevv CRAS X DDR4 3600MHz, 16GB RAM
- MSI A750GL PSU

I had the same problem a few weeks back. Everything seemed fine until I realized that a recent Windows update might have caused conflicts with some games. Try rolling back any recent updates or checking game-specific forums for similar complaints. If that doesn't work, it might help to run a few stress tests to see if the PSU is really the culprit.
I had a similar issue not long ago with specs like yours. Initially, I thought it might be a software issue, but after running some hardware tests, everything checked out fine. Have you tried looking into potential power supply issues? Sometimes, a PSU can cause shutdowns even when the temps seem normal. It could be worth checking if it's properly delivering power under load.
