This computer seemed great, out of the box. Hooked up easily, worked fast -- considering our previous computer was 12 years old!  Then after about 4 days, it quit.  Assumed it was "asleep" and it would not "wake up." Tried turning off, and it turned back on by itself -- or at least the power button lit up and one of the fans inside came on. That was it. No start up of software at all.  So, returning it to get a replacement. Hopefully it lasts more than 4 days!
