MSI netbook web cam gone

I have an MSI netbook about 6 months old. Win 7 premiun. On board cam.
The cam has gone.
It does not show in device manager or on any programs.
Suggestions?

Two options that immediately come to mind:

1. Try using Windows' "System Restore" to roll Windows back to a previous state when your computer was functioning correctly:
   
   
   
   • Microsoft.com > System Restore > Windows 7
     http://windows.microsoft.com/en-US/w...System-Restore
   
   
   
2. Get it repaired under the one year warranty.
