Built in Webcam Problem

Every time when dealing with a driver issue there are 3 things to think of:

1-Is the driver installed?
2-Is the driver up to date?
3-Is the up to date driver compatible with the OS?

1-Install the driver using the CD that comes with the hardware.
2-Install the up to date driver from the website of the hardware manufacturer.
3-If the up to date drive not compatible with the OS, and still having problems then uninstall the driver, restart the computer and then let the OS install the driver automatically. (yalle byerta7lou, khalli ydabber rasou!)

If you still have problems, then dear user, either your hardware is damaged or it is not compatible with this OS and in this case you have to wait for a HotFix from the OS company or wait for a new version of the driver that contains a fix for this problem.
