This certified refurbished computer failed to boot.  I have a graduate degree in programming, and have built a few computers myself, so it isn't like I don't know how to plug in a new computer.  It is simply a case of them saying that it was fully tested, when it wasn't.  Now I have to wait for another computer.  This is not the first time I have purchased a refurbished item from Amazon only to find that what I received was not what was advertised.
