Trying to format and install Win8 on this machine. It came in with a problem and she just wanted win8 on it. It starts and see's the DVD then the win8 logo pops up and it stalls. I have also tried win7 (original) and xp and they all stall at the same spot. XP stalls at starting windows and 7 stalls as soon as you see the win7 splash screen. I have also tried removing the hard drive, different memory and a different DVD and it just stalls. At one point win8 said there was a hardware issue and it was gathering info but it just stalled there. This machine is a all in one with a touch screen.
