Freeze at boot time F9

[Greg12866]

I can't seem to get F9 to boot..It goes through the install ok,but after i add my user name and password and X tries to start the computer freezes...I reboot and it sends me back to the enter user name and password screen,when i put the user name it says it already exists and asks if i want to login with that user..I say yes, and the same thing happens... I have never had problems with Fedora booting...

Any advise?
