Was just watching a twitch stream and playing a browser game (OSRS) and my computer just restarted, screens when black and it automatically restarted with no errors. No error messages/popups and the event viewer showed a critical error. No dmp files were created. Monitored temps after and everything was fine. Any ideas? Is it just a fluke/glitch?

I5 4690
GTX 970 - 359.06 drivers
16gb kingston hyperfuryx
Corsair CX750M
250gb Scandisk SSD
1tb WD blue HDD
Running Windows 8.1 that is fully up-to-date with all the drivers ect...

Solution
Power fluctuation. It was a fluke in the power system.
You'll have 1-2 like this / year. If they get more common consider replacing the PSU or buying an UPS.
