(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". (1998-09-08)
