I had this PC for 24 hours and then it died.  When I press the on button, the PC beeps, while the CD-Rom and SSD lights flash.  The PC doesn't turn on.  It just continues beeping and flashing.  Thankfully Amazon has a 90 day warranty on refurbished PCs.  I don't know if I'm just unlucky.  This is the second refurbished PC I bought.  The first Dell I bought lasted 30 days and then I got the "black screen of death".  I figured it was just bad luck so I bought this PC  next.  This PC lasted just 24 hours.  I don't think I'm going to buy a refurbished PC again even though it pains me to pay full price at Dell.com.
