I used this machine for about two months before it suddenly crashed and would not boot the operating system.  Took it to a local computer repair shop hoping that it was something simple, but it was not.  They wiped the system clean (including files I had stored locally) and reinstalled Windows at a cost of $65.  It worked for another two-weeks or so, at which time it crashed again with similar symptoms, i.e., would not reboot.  I was extremely fortunate that it malfunctioned again before the September 5 return deadline.  I did get a full refund, but encountered many hours of frustration and time lost in the process.
