Blue Screen of Death in Windows 10.

A Blue Screen of Death (BSOD), technically called a STOP error, occurs when Windows suffers a serious error and is forced to "stop" completely.

BSOD errors can occur in any Windows operating system, including Windows 10, Windows 8, Windows 7, Windows Vista, Windows XP, and even Windows 98/95.

Since a blue screen error gives you no choice but to restart, troubleshooting one can be difficult. Fortunately, almost every STOP error includes a hexadecimal-based STOP code that can be used to research a fix.

Below are links to information on individual STOP errors including what each STOP code means and any troubleshooting information we have, or have found elsewhere, on that blue screen error.

Note: We highly recommend checking out any links to specific information on your particular STOP code in the list below, but if we don't have a detailed solution, especially if the BSOD is uncommon, see the How to Fix a Blue Screen of Death guide instead.

Tip: All STOP codes below are listed in order - see How to Count in Hexadecimal if you get lost trying to find yours. If you still have trouble, you might try searching for the BSOD error code using your browser's page search feature (usually invoked with the Ctrl+F keyboard shortcut).
