Windows 10: PC reboots by itself since Win10 upgrade

Ever since I've upgraded to Windows 10, my computer randomly reboots (from hibernation mode). Once it was exactly at 3:00 AM, the other were random times. The spookiest of all times was when it randomly booted, I shut it down, and then it booted again five minutes later - two times in a row. I took a look into the Event Viewer, and the first events are as follows (I have to freely translate as I haven't been able to make my German Windows display the events in English):

- System time was synchronized with the hardware clock
- The firmware has sent start metrics
- In this system there are 0x1 start options
- The start manager waited 0ms for a user input
- The guideline for the start menu is "0xFEC00000"
- The start type was "0x2"
- The system got reactivated from standby. ... [some timestamps] ... Reactivation source: unknown

This has happened more than once (although I can't say for sure that this was always the reason for the unprompted reboot).

I know there are some options to prevent Windows from rebooting, but firstly I'd like to establish the causes as I'm kind of unsettled right now....

n95 reboots by itself...

Which FW version do you have?

*#0000#.

 

I'm having the same problem!
it happened suddenly before i save the project i was working on!
this sucks!!*Mad

 

Interestingly, I seem to be having the same issue with my laptop, equally upgraded to Windows 10 recently. The status messages in the event viewer there were the same... I also did a virus scan, which didn't turn anything up (which is not equal to 100% security, I know).

 

Have you set the system failure default to NOT automatically restart? This should leave the error report on the screen instead of rebooting. Might be helpful for finding out the cause of the restart.

(Ctrl Panel\System\System Protection\Advanced tab\Startup and Recovery Settings\Uncheck Automatically restart).

 

Well, I was a bit ambiguous about the boots. The rebooting after an update was because of an "automatic update" setting, which I have now fixed. The problem of random boots from hibernation remains.
