Computer started  and after about 1/2 hour  completely shut down on it's own!  Would not restart!  Instead it would  make a whining sound  then  the fan appears to  start blowing.  In fact  I am  EXTREMELY  DISAPPOINTED  in  this  computer.  It is  a piece  of  JUNK!  Since  the lowest  rating is  1, I had to mark it  as such.  BUT  I would  have  actually given  it a rating  of  is less than  ZERO!
