STOP Messages and Error Message guides.

[RASTABT]

STOP Messages literally mean Windows has stopped! These appear only in the NT-based operating systems: Win NT, Win 2000, and Win XP. Most are hardware issues. STOP messages are identified by an 8-digit hexadecimal number, but also commonly written in a shorthand notation; e.g., a STOP 0x0000000A may also be written Stop 0xA. Four additional 8-digit hex numbers may appear in parentheses, usually unique to your computer and the particular situation.
