Built-in Webcam Trouble

[apric23]

I have a Compaq Presario C769US Notebook PC with a built-in webcam. When I got my laptop about a year ago, I tried out the webcam, which worked perfectly fine at the time. However, I recently tried to use it again, but the program I used said there was no video device detected. I have searched everywhere but cannot figure out what I need to do. Whenever I open the device manager, there are no imaging devices - the tab does not even appear. Everywhere I go says to download drivers, but my computer is acting as if the hardware isn't there. What should I do?

Is it running the same operating system as a year ago ?
or did you maybe upgrade to Vista ? and no driver for it ?
