Hi,
If the computer shuts down while watching videos, restart the computer and open event viewer and check for error logs and post them here.
- Open Event Viewer by clicking the Start button, clicking Control Panel, clicking System and Security, clicking Administrative Tools, and then double-
clicking Event Viewer. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
- Click an event log in the left pane.
- Double-click an event to view the details of the event.
Refer this link for information on event viewer:

This issue can also occur due to a third party program conflict. I would suggest you to perform a clean boot and check if the issue resurfaces again. With
the help of clean boot, we can isolate the conflicting program or service and disable the program to fix the problem.

If this resolves the issue, then see the Microsoft Article on “Clean boot” mentioned above and the section “How to determine what is causing the problem” to determine which program or service maybe causing the issue.
