Windows 10: Strange Hang on system reboot

So this has happened a cpl of times recently. First time I forgot to look at the time on my pc so was hard to see in event viewer. My clock was stuck at 330 this afternoon, event viewer says the system rebooted unexpectedly at 330. Yet its 715pm and my computer was still just as I had left it this morning.


Nothing really worked i.e. web browser didn't load fully just a white screen Task manager worked, sort of, I could see the things in my taskbar window but loading them either didn't work or never fully loaded. When I tried restarting I had to do so by ctrl alt del but it still just sat on "restarting".


Had to manually restart and now everything is fine again, any ideas? HDD failure? possible power supply failure?


Thanks in advance

Computer Constantly Rebooting

is that reboot periodically? If periodically could connected to heat or software, if it random could be from hardware.
Try to release the board off the case then check it again, it could be from short circuit or something
if the system is on, there any strange on the system? Like get hang, fan spinning too fast, bsod or something

 

Continual System Reboot

There is a possibility that this issue might have occurred due to corrupt system files in the system.

So to diagnose whether there are no corruptions, we suggest you to try the following methods and check if it helps.
