I have an inspiron laptop, about a year old now and the integrated webcam has randomly stopped working. The light still comes on but on webcam central, msn, skype and every other programme i have tried, there is no picture. I also keep getting a pop up in the bottom right hand corner of my screen saying 'USB Device Not Recognized' over and over again, even though there is no USB inserted. I don't know whether the two problems are related but they started happening around the same time. I'd really really really appreciate some help with this, its driving me absolutely mental.

Thanks
