PC restarted itself. "System failure"

[Lemonpearl]

I was just using Chrome (one tab) when it happened. However, I have yet to encounter problems while gaming and Heaven benchmark looks fine. I've also been experiencing crashes (e.g. black screen with movable cursor, or multiple programs will just stop running). 

 

I have turned off the "automatically restart" option under "system failure" in Advanced System Settings, so I can see the blue screen error message if it happens again.

 

What are the possible causes/fixes?

 

These fixes have not worked:

DDU and install newest Nvidia driver.

Removed malware.

System file checker.

 

EDIT: I think I found the error in Event Viewer. Critical. Event ID: 41. Source: Kernel-Power. The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

 

EDIT 2: I changed sleep settings to "never" under "hard disk" and "sleep" in advanced power settings.

Do you use a UPS? If not, it could have been a lag or spike of your power.
