I recently purchased 8.0 Personal. I decided to do a clean installation, so I deleted my existing 7.3 partitions and booted from the first CD. When I got to the "Detecting Hard Disk Controllers" message, my mouse pointer became extremely slow to respond to mouse movement. By the time all hardware was detected and it was time to move to the next step, both the keyboard and mouse were 100% unresponsive. So I pressed the reset button and installed 7.3 (which works perfectly), thinking perhaps an upgrade to 8.0 would work. It did not, I got the same results. I tried installing 8.0 in Safe mode, no change in results there either. Any ideas/suggestions? Right now i'm assuming that the hardware detection process pokes the motherboard somewhere it doesn't like. It's also worth mentioning that my mb has no ps2 keyboard or mouse ports, it's AGP only.
