I switched to Windows 11 about a year ago. A few months ago my PC started randomly crashing and rebooting, without any blue screens.
Am I the only one? Does someone know anything about this?
Pretty sure I can rule out power surges or overheating or stuff like that. There’s been no indication. The system log is empty as well, apart from Windows being annoyed that it just got restarted without any notice.
Sounds like a faulty PSU. I had that happen and it went away as soon as I got a replacement. GPUs can cause power spikes beyond the specifications in the millisecond range, causing the overload protection of the PSU to kick in and shut down the PC. This causes no bluesceen and creates a reboot instead. It’s hard to track down because the windows error log can say all sorts of things.
Alternative remove your GPU driver via DDU uninstall tool and clean install it. I also had one system that didn’t like TPM enabled, but it’s basically requirement for win11, so.

Obligatory: You should ditch windows and install Linux instead
Now, with that out of the way:
Sounds like a hardware problem. Is this a stationary or a laptop? How have you ruled out overheating? Keep in mind that there are more things than the CPU that can overheat.Restarting like that, it’s either overheating (reaching 100°C) but you ruled out that, so low voltages, maybe some voltage on your PSU is weak, sometimes a 1.3V becoming 1.2V and it reboot.
+1 PSU
My friend had this issue recently, it turned out to be his CPU overheating, his event log also showed no details of the cause, it was only when he installed a temp monitor and kept it open on his 2nd screen that he saw his CPU was hitting the max allowed temp just before getting the power cut.
Hope you manage to get it sorted
