Buzzing sound when watching a video followed by shutting off

[AC Question]

It just started doing that. In the middle of watching a video, it made a loud buzzing sound and shut down. It restarts and works just fine. Battery wasn't low either. It wasn't due to overheating either.
Has this happened to anyone else? I've read on here that some have experienced the buzzing but noone has mentioned that it happens specifically during a video

Well it could be your device protecting itself from malware if you were watching the video on a third party site.
But if it buzzed, and maybe the screen buzzes off. It might not be over heating, if the back was cold, that means the cores quickly shut down to prevent the battery from overheating. If the battery was cool or cold that means it is internally damaged. And you need a new one.
