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
 
Solution
Found the cause last night. The restarts were most definitely cat-related. Solved temporarily by taping a small box over the reset button on the PC.
Last 3 nights I have that but then last 3 nights I have unplugged my PC after turning it off and due to way fast startup works, I know why I got those errors. I assume you aren't unplugging it though.

So you leave PC asleep all night?

What are specs of PC?

 
I too have had same issues for the last week. Mine is not always at the same time. I get the reboot back to login screen after several hours of idle status. I have done a memory check, integrity check all is good. checked all other drivers all are up to date. Not sure where to go from here, its not causing an issues at this time, but afraid it may manifest and get worse with time. So, any suggestions are welcomed too. I did download harcdware info and see no errors so, confused.
