(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)
