Hi all,   this is my first post with this computer, so I hope I am in the correct section.   I have a Dell Inspiron 15 3521 laptop, running windows 8.   I have not had this computer very long, and I have mistakenly deleted Bluetooth from the start screen.   My wireless is working, but the integrated webcam has disappeared.   I have gone into Device Manager, and clicked on the imaging devices, and the only thing showing is the printer which I have connected.  No camera is shown at all.    Having googled the problem, it seems that I have deleted the driver for the Bluetooth as my Bluetooth folder is empty.    I do not know what to do, can someone please help me.

I have checked on "my dell" and I can download drivers for Bluetooth, and there are a couple,  but I am not sure what to download, and also I understand drivers have to be installed in a particular order,   everything is working on my computer fine, apart from the fact that I do not have an integrated webcam anymore.   I don't want to mess up my computer by downloading incorrect drivers, but equally I would like to have my webcam back,  so is there anything I can do please to get this back, and also how to do it please.  Any help would be much appreciated.

Thanks for any answers in advance.
