Inspiron 1520 No Camera Detected HELP! My Dell Inspiron 1520 Webcam Isn't Working?

HELP! My dell inspiron 1520 webcam isn't working? - inspiron 1520 no camera detected

A month ago, my Dell Inspiron 1520 laptop crashed and I was blue checked. I called Dell support high technology and new disk sent me to reinstall all programs. It worked and my laptop is working again, with the exception of the webcam. I need to install Dell Webcam Center, and when I try, the camera is the camera that says "Unsupported recognized:" This is wrong, this notebook comes with an iSight. Who knows what's going on?

THANK YOU!
