LOGITECH QUICKCAM...........CAMERA FAULT UNDER WARRANTY.

Hi Tony sounds like you have a driver problem
If you haven't updated your software since you installed it - I would recommend this :-
Unplug your webcam
Uninstall the current logitech software
Restart your computer
Visit the Logitech website - Identify your camera - click on it and download the software
note - there are 2 pages of webcams on the bottom of the first page look for the 'Still cant find your webcam?' link for out of production models
Uninstall the current software

open up the control pannel for the microphone and turn the volume up and re train the microphone. If you have forgottent how to do this please post here and I will walk ypu tjrew it step by step.
