I am having a bit issue with HP Pavilion DV6-1030CA system. It is a nice notebook on which there is Windows Vista on the same. Somehow I am not able to use webcam on it. While all other stuff works fine. There is no problem at all. I am getting a constant error on my screen when I am trying to access the webcam through yahoo messenger. The error is no video device detected. What should I do to fix the problem.
