Webcam

My webcam (HP Pavilion dv6000 lap top) works well for about 10 minutes or so, then it will all of the sudden stop and then I get an error messgae that says the webcam is not connected. The ONLY way I can get it to work is if I reboot. I can not seem to find any info on the situation on the web or any help. Does anyone know how to fis this?
