Just so I'm clear in my own mind, when you say "done install #6", you mean this to be the complete Windows install? Also, when is the "Loading operating system...." appearing? During the install? Did the PC reboot a couple of times during the Install? Did you ever get to a Desktop?
Did you do the Configuration Mode for the motherboard? This should have cleared CMOS and basically rendered the motherboard "new".
I just want to make sure you're following the steps to completion.
