My webcam can no longer be accessed after I upgraded to windows 7.

Hey,
I upgraded to windows 7 a while back and I recently discovered that I can no longer access my webcam (built-in) anymore. I have a HP Pavilion dv6 Notebook PC. I have tried searching for it in all my files and I've chhecked 'Devices and printers but have had no luck. Although my webcam still works for skype and I've have looked for it's files whilst it has been on but I can't find anything. Can someone help me please. Thank-you

The drivers might not have loaded or laoded properly with the upraded. Check out HP's website and downlaod the driver/software f rom there.
