I've been dealing with some frustrating random black screen crashes on my Windows 11 PC, and I'm trying to figure out if it's due to my GPU or PSU. Here are the symptoms I've noticed: the screen just goes black with no mouse movement or signal; the shortcut Win+Ctrl+Shift+B doesn't bring the display back; and after about 1 to 3 minutes, the system restarts all on its own. These issues occur both during gaming sessions and even when I'm just idling or using light applications, like Office.

First off, try reseating your RAM and GPU. Sometimes just making sure they’re properly connected can work wonders. Let me know if that helps!
It’s a bit perplexing, for sure. Have you considered checking the overclocking settings? With four sticks of RAM, it can make the CPU throttle and draw more power from the PSU, which might be causing the crashes. Also, keep an eye on your BIOS settings—make sure your RAM is at factory defaults. Also, I heard there were some issues with the latest Windows 11 update causing similar problems. Might want to look into that too!

I will try that!
