If you’re here, your computer shut down unexpectedly, as indicated in your system’s Event Viewer. When this happens, it’s important to find out why the system shuts down randomly to determine if there’s a course of action you must take to resolve the issue.

Whichever is the case, Windows 10 features various built-in tools that you can use to check the time, date, and reason your system restarted or shut down suddenly. This article shows you how to use the Command Prompt, PowerShell, or Event Viewer and other options to investigate a sudden shutdown.
