Not sure what's going on with my PC. I just wake up in the morning and a reboot has happened. Event viewer shows the following line:
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
Restarts happened at 1:45 and 2:01 am on the 24th and 25th, respectively. Malwarebytes detects no malware, and Windows Update last updated a week prior. There is no indication of what may have caused it in Event Viewer, and thermals appear to be fine. Power has flickered a few times, but the PC is on a working UPS that keeps it running, and I have witnessed it work during daytime hours. There are no crash dumps available. I'm out of ideas for diagnosing this, and would appreciate any suggestions.
Edit: Forgot to mention, running Windows 10 with full updates
