Yeah I get to the windows log in screen and it plays the intro tune but really laggy, sometimes it will prompt you to enter a password and other times it just shows the windows background.
been doing some more playing around and if I f10 to save changes, the bios attempts to reboot the machine, if I hold the power button before it posts to force a shutdown then next time it works fine. I can tell if its work or not as the screen that prompts you to press f12 or delete for the bios disappears quickly, but when its going to fail it stays on that screen for a few seconds.
