I'm trying to upgrade my ASUS system from XP Pro 32bit to Windows 7 64bit. I ran the Windows 7 Upgrade Advisor and everything checked out okay except for a warning that my system would not support the Windows Aero graphics capability. When I insert the Windows 7 64-bit disc, I get an error message saying my system is not compatible. Any ideas on the steps I should take to figure out what is not compatible would be appreciated. I also tried formatting the HD and doing a clean install of the 64bit version. I selected "Boot from CD". The system just hangs at the "Starting Windows" screen.
