Don't install catalyst, if it's installed, remove it.
Boot into safe mode, remove Catalyst and your 3400 drivers.
Restart into your bios, set default graphics card to PCI Express, discrete, and disable switchable graphics.
Save, Restart.
Have windows use windows update to try to find drivers for your card, the version I have working now is from windows update.
(if windows insists on using the driver in the catalyst temp-install directory, just delete the directory from safe mode... I think its default C:\Ati or something simple?)
