Sound Laptop stops recording

Desparate:
Recording. Everything OK. Suddenly loud continuing noise from laptop stops track recording. Cut off monitors. Laptop speakers keep the loud noise going. Cut off Cubase. Sound stops.
The longer I work on one track, the sooner it starts. Maddening. I want to record, I’m not much of a pc man. What is going on? Does someone know?

Wait a few days until my crystal ball that let´s me see, which Hard- and software you are talking about is back from repair…
