CPU fan adjustments happen unpredictably, leading to monitor instability and necessitating a full system restart.
I've observed that my CPU fans increase speed unexpectedly, which leads to my monitor shutting down and requiring a hard reboot. This happens during long sessions of modded Skyrim or even when logging into Windows 10. I ran a stress test using Prime95 and noticed the problem around 75°C. While it might be related to the fan, it doesn't seem to affect power loss on my monitor. High temperatures on the login screen or while browsing aren't unusual for me either. Could this indicate a CPU issue?
Your monitors aren't connected through your PC, they're not turning off on their own—it's because the computer isn't sending a signal anymore. There seems to be an issue with the system, causing fans to run at maximum speed. It looks like your hardware is consuming more power than your power supply can handle.
It's not uncommon for CPU fans to reach maximum speed when the power supply isn't delivering enough power. Your setup has been running smoothly for years, so it's possible the PSU simply wasn't providing sufficient output over time. The fact that you're now using a more demanding GPU doesn't necessarily mean the PSU failed, but it could be a sign of reduced capacity.
