Hi - I'm trying to install FC3 on an AMD 64 system, with Windows XP already installed. FC3 has stopped xp from booting (I installed grub on the MBR) and although FC3 worked alright for a while, it now won't boot properly itself. Either i get strange pixel patterns at the top of the screen after I log in, or it logs in and then the mouse freezes and I have to reboot. Can anyone help - should I reinstall the MBR with windows and try again - I've already reinstalled FC3 3 times, but I want to keep plugging away at it. thx Tarn
