Intermittent problems

A term often used in IT, Warranty repairs or Electronic repair in which a device such as a graphics card, gives faults at irregular intervals. A lazy fuck then refuses to fully test the device and then just defines the fault as "Intermittent problems", letting someone else, usually the manufacturer, resolve the problem.

Tech1:"this client says it randomly shuts down"
