Blue screen of death

The blue screen of death (also known as BSoD, blue screen error, blue screen, fatal error or bugcheck, and officially known as a stop error^[1]^[2]^[3]) is a critical error screen displayed by Microsoft Windows. It indicates a system crash, in which the operating system reaches a critical condition where it can no longer operate safely.

Possible issues that can cause a BSoD include hardware failures, an issue with or without a device driver, or unexpected termination of a crucial process or thread.
