Do you know if the web camera ever worked and if so, when did it stop working?  Did your notebook ship with a web camera? They aren't always included by default, if you didn't order one while purchasing the notebook it may not have shipped with one.  

The web camera on the N5050 uses native Windows 7 drivers.  If you have installed all the needed drivers the webcam should install itself.

Since you have just reinstalled Windows please make sure that you have installed the chipset driver, its absence could certainly cause problems with all USB devices, not just the webcam.  You can find the chipset driver on the following link.
