Alienware 17 R3 Laptop Bluetooth has disappeared Win 10

Hello, first I'd like to apologize if this has already been posted, but I couldn't find anything that specifically dealt with it.  Today (12/28/15) when I got up and turned on my computer, everything was fine, and the Bluetooth symbol was there, it was on, and all was right with the world.  This evening, I was working on my computer, opened up my Fitbit app.  It has a message that Bluetooth was turned off.  I thought that was weird so I clicked on "show hidden icons" and the Bluetooth icon was gone.  I went in to "settings," clicked on "Devices, Bluetooth, Printers, Mouse," and the Bluetooth category was gone.  I went into device manager, and don't see anything in the list that has anything to do with Bluetooth.  So basically, I'm at a loss.  I don't know how the Bluetooth can just disappear.  I haven't done any updates, and I was away from my computer most of the day until this evening when I discovered the issue.  Has anybody else had this issue?  Is there someway I can get it back?  I did make a recovery flash drive a few weeks ago, but I don't want to go that route unless I need to.  Any help would be appreciated.
