Blue screen of death

A blue screen of death (also known as the blue screen, bug check, BSOD, or Stop error) is a common name for the screen that occurs during a system crash in Microsoft Windows operating systems. It is shown when the operating system can no longer function safely due to a fatal system error.
Although fictional versions of Windows and fictional operating systems also have blue screen of death and hidden Windows or fictional OS startup/shutdown sounds.
