black screen issue

The black screen of death (BSoD or BkSoD to distinguish it from the blue screen of death) is a screen displayed on many computer systems after encountering a critical system error. It gets its name from the black background seen during hardware or software errors.
Some versions of Microsoft Windows prior to Windows 11 version 24H2 (and to a lesser extent, macOS) also display a black screen of death upon fatal system errors, usually caused by several factors.
In newer versions of Microsoft Windows since Windows 11 version 24H2, a black-colored blue screen of death ("BSoD") is used to indicate a system crash, where the operating system reaches a critical condition where it can no longer operate safely.
