After installation of Fedora 17 the screen is going white on reboot

I have installed 32 bit fedora dvd iso in my system.
the installation went good, i have selected GNOME for my desktop environment.
I have a RADON 66xx series graphics support.
however after installation at the time of reboot, the screen is going white instead of login page. and hangs there....
a quick response and a solution will be great...

Which kernel are you using?

Try to boot the original 3.3.4 kernel or install the proprietary catalyst drivers from rpmfusion

yum install kmod-catalyst
