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 the Microsoft Windows operating systems. It indicates a system crash, in which the operating system reaches a critical condition where it can no longer operate safely.
Possible issues that may cause a BSoD include hardware failures, an issue with or without a device driver, viruses, malware, and other factors.
