Inspiron 15 3537

Just received the Inspiron 15 3537, Win 7 Pro, yesterday and there is an incessant clicking noise coming from what I assume is the hard drive.  This is for a business and this noise is unacceptable, no one in our office can work with that constant clicking. 

We're going to return it if it's not resolved.  Sent an email to Dell tech support so we're just waiting for an answer.

Has anyone else had this issue?
