My Alienware M15X has an integrated webcam and when I got to open Dell Live! Central, I get a blank black screen where the webcam images should be, and at the bottom of the window there is the notification: "No Supported Webcam Connected".
I got my laptop in December last year (2010) and it was working but something must have happened to it, possibly an update or something, and now it won't work, ive tried reinstalling it from the Live! Central disk but still get the same result.
To make matters worse, the integrated microphone won't work also, so I don't know if i have to download some drivers or completely reinstall Windows 7.

Any help would be wonderful,

Thanks in advance!!!!
