Computerworld - A computer that monitored drilling operations on the Deepwater Horizon had been freezing with a "blue screen of death" prior to the explosion that sank the oil rig last April, the chief electronics technician aboard testified Friday at a federal hearing.
<...>
The machine had been locking up for months, Williams said, producing what he and others on the crew called a "blue screen of death." "It would just turn blue. You'd have no data coming through," Williams said today, according to the New York Times' story.
With the computer frozen, the driller would not have access to crucial data about what was going on in the well.

Microsoft declined to comment on Williams' testimony and characterization of the crash screen.
