My fiancé bought this computer twice now. 2 different senders and this one was Amazon certified. How can something be Amazon certified when one the pervious owners information was still on there and two when he tried to do a factory reset he found out the hard drive was fried. He took hours following instructions to fix it to only find out it wasn't fixable.  Tried to talk to someone at Amazon todo a exchange and all they said is they can refund it because they had no more left,  when the selling page said that had 6. That's upsetting. Who ever is in charge of checking these computers should not be in that position because it's obvious that there not doing there job. Very disappointing. My fiancé needs it todo his job as a DJ.
