The Black Box of Death

The Black Box of Death (also known as a box error or BBoD), is an error screen displayed on all Reler operating systems after a fatal system error, also known as a system crash: when the operating system reaches a condition where it can no longer operate safely.

History
BBoDs have been present in Reler v1 (the first version of the Reler family, released in 1994) and all Reler operating systems released afterwards. BBoDs can be caused by poorly written device drivers or malfunctioning hardware, such as faulty memory, power supply issues, overheating of components, or hardware running beyond its specification limits. In the Reler 1x5 era, incompatible DLLs or bugs in the operating system kernel could also cause BBoDs. Because of the instability and lack of memory protection in Reler 1x5, BBoDs were much more common.
