Webcam connection problem

I have been enjoying my HP Vista computer. Works very nice and fast.

I have had one problem recently: it seems the monitor (or webcam) of my laptop has a loose connection. If any time during a Skype call I move my monitor (screen) up or down -- I loose my webcam picture. The blue light next to the camera still lights up -- but it produces no picture. And there is no way to get it back. I have tried closing and quitting Skype -- still nothing.....

The only way I get the webcam to work again is to restart my computer! Then we have the pictures back.

The whole procedure (of restarting the computer) takes me around 10 minutes.  

Question: Might there be any easier way to get the webcam working properly than restarting my (Vista) computer?
