Blue Screen of Death

(Computers) blue screen which appears on PCs running Microsoft Windows operating system when a serious system error (often a general protection failure) has occurred

A Blue Screen of Death (also known as a stop error, BSOD or bluescreen) is an error screen displayed by certain operating systems, most notably Microsoft Windows, after encountering a critical system error. Bluescreens can be caused by poorly written device drivers, faulty memory, a corrupt Registry, or incompatible DLLs. Bluescreens have been present in all Windows-based operating systems since Windows 3.1; OS/2 and MS-DOS suffered the Black Screen of Death, and early builds of Windows Vista displayed the Red Screen of Death after a boot loader error.

<humour> (BSOD) The infamous white-on-blue text screen which appears when Microsoft Windows crashes. BSOD is mostly seen on the 16-bit systems such as Windows 3.1, but also on Windows 95 and apparently even under Windows NT 4. It is most likely to be caused by a GPF, although Windows 95 can do it if you've removed a required CD-ROM from the drive. It is often impossible to recover cleanly from a BSOD.
The acronym BSOD is sometimes used as a verb, e.g. "Windoze just keeps BSODing on me today".
