noise pick up when recording streams.

Good morning, I’m recording from you tube various albums but when I play the cds I’ve burned I have background noise from me moving or coughing during the recording, any suggestions please ? I’m not that brilliant at IT being a so called silver surfer so not too technical terminology please, thanks John P.

There are several ways to do that (see: Tutorial - Recording Computer Playback on Windows - Audacity Manual)
Which method are you using?
Do any of the methods described on that page work? (“WASAPI loopback” is usually the most reliable).
