I had a similar problem with a built in web cam in my Dell laptop..when I did a clean install of windows 7, the web cam no longer worked. Im not sure if your laptop is a Dell or not, but if it is, you will need to download the Dell webcam manager from the Dell support site. Im not sure if you used a OEM disk or not, but if you just used a retail copy as i did , your software that came bundled with your pc will no longer be there and you will have to reinstall the OEM software that you want. Hope this helps.
