macOS Sierra - auto restart when watching youtube videos on full screen

After the upgrade, from El Capitan to macOS Sierra, whenever I try to watch youtube videos or any online videos on full screen, the computer just automatically restarts itself, why?? Anybody with a similar problem?

MacBook Pro, macOS Sierra (10.12)
