    Open Event Viewer

    ~15s
    Search "Event Viewer" in the Start menu. Or press ⊞ Win+R, type "eventvwr.msc," and press Enter. The main window shows categories on the left.

    Check for errors

    ~15s
    Expand Windows Logs > Application or System. Look for red circles (Errors) and yellow triangles (Warnings). Click an event to see details below. Recent errors around the time of a crash are most relevant.

    Understanding entries

    ~15s
    Level: Error (red) is a failure, Warning (yellow) is a potential issue, Information (blue) is routine. Source tells you which program caused it. The Description field explains what happened.

    Search for help

    ~15s
    Copy the Event ID number and source name. Search online: "Event ID 1000 Application Error." You'll find specific solutions for that exact error. Microsoft's support pages often explain common event IDs.
