See if there is an "Imaging Device" -- your webcam there.
If it is check Properties (Right-click). If it shows device is working properly, then it is there and working. You just need a program that accesses it.
If it is not there:
Go to the Dell Support page, enter your service tag and look in Device drivers. Find the one for you camera. Download and install it. If you cannot find that specific driver, download and install the Chipset driver.
If it still not there, you can find a USB Webcam on Amazon for about $30 Cdn.
