4 months out and this thing is dead in the water.  Amazon's answer. Sorry to hear that...no refund.Here update to this unit l took this unit to a friend who did what he called a hard boot. He got the unit to boot but it would not stay booted. It kept quiting.  He was able to back up my things on the hard drive.  He suggested that l do not invest in more money in this unit.  He agrees with what Dell told me.  Dell told me and your agent who was working with me that"this unit is obsolete. Dell said that this unit is 10 years old".  My friend also pointed out that starting next year windows will not support window 10.  Therefore the unit will be unsafe for Internet use.  My told to keep the hard drive and junk the rest of this thing.
