System unexpectedly powered off on a computer.
System unexpectedly powered off on a computer.
Your PC has been shutting down unexpectedly after extended use. The issue appears to be related to system instability, possibly from hardware changes or software conflicts. Your GPU and CPU temperatures seem normal, which rules out overheating as the main cause. The problem started after upgrading components and switching games, but now persists after switching back to Windows 11. The RGB on your motherboard and RAM stays active, yet the RAM display freezes. This suggests a potential conflict between the new OS and your hardware setup. Consider checking for driver updates, testing with a different USB port, or consulting manufacturer support for compatibility issues.
Consider using MemTest86 for thorough RAM checks. Visit its official website for more details. Simply plug it into a USB drive, boot it up, and run the tests. This will help ensure your system's memory is functioning properly.
This situation is different from when the system is under load. As bmx noted earlier, it would be simpler if we had complete system details. He also pointed out the Windows Event Viewer as something to check. I’m not comfortable with memtest, so I don’t know how to assist there, but you might try other stress tests like OCCT (which includes memory testing) or Cinebench.
I own a Ryzen 9 7950X processor, an NVIDIA RTX 3080 Ti graphics card, an X670E-E motherboard, a Dominator Plat platform, 32GB of DDR5 RAM at 5200MHz, and six Corsair 140mm fans.
