A user's computer unexpectedly shut down immediately after the user plugged in a USB headset.

Event Viewer is a Microsoft tool that records and displays system events, errors, warnings, and information. Event Viewer can help troubleshoot and diagnose problems, such as unexpected shutdowns, by showing the details of what happened before, during, and after the incident. Event Viewer can also show the source of the event, such as an application, a service, a driver, or a hardware device. By using Event Viewer, a technician can identify the root cause of the unexpected shutdown, such as a power failure, a thermal event, a driver conflict, or a malware infection.
