Unplug USB devices and try again.
But what tools do you have to fix this? A real XP CD comes in real handy.
I'm helping someone with a problem booting their system. They are running Windows Media Center. The computer gets past the Windows logo screen and then the screen goes black and stays there. When I try to come up in Safe Mode, it gets as far as MUP.SYS and freezes. I don't know if that means that MUP is the problem or if the problem lies with whatever might be trying to load after MUP. Any suggestions or guidance would be appreciated.
