Troubleshoot blue screen errors

A blue screen error (also called a stop error) can occur if a problem causes your device to shut down or restart unexpectedly. You might see a blue screen with a message that your device ran into a problem and needs to restart.

Note: If you are experiencing a black or blank screen error, see Troubleshoot black screen or blank screen errors for more info.

On this page, we’ll take you through a series of troubleshooting steps to try and help you figure out the cause of the blue screen error and how to resolve it. 

The steps in this article are intended to help troubleshoot common stop error codes, such as the following:

  • CRITICAL_PROCESS_DIED

  • SYSTEM_THREAD_EXCEPTION_NOT_HANDLED

  • IRQL_NOT_LESS_OR_EQUAL

  • VIDEO_TDR_TIMEOUT_DETECTED

  • PAGE_FAULT_IN_NONPAGED_AREA

  • SYSTEM_SERVICE_EXCEPTION

  • DPC_WATCHDOG_VIOLATION
