I got this problem with my HP Window Vista notebook internal webcam. I bought it for over $650 and i have used it for about a year now. It still very new but one thing i don't really like from it is that the speed is very slow that i can not even manage. Recently, when i try to turn it on, the webcam couldn't display any more. I have tried all i could but still no solution. Any help on how to upgrade the speed and web cam problem will be highly appreciated.
