Radeon HD4350 and Windows7 Help Please!

I am having a problem getting this card to work with Windows7 64bit at 640 x 480 at 15khz.

I have tried with catalist 10.0 and 10.3.

The steps I have tried are:

Install drivers, set resolution using quick res to 640 x 480, install soft 15khz then reboot. Windows then restarts still in 60khz at 640 x 480 on either dvi or vga.

If I run soft 15khz again it says it is active. The strange thing is if I start up quick res again 640 x 480 is now missing from the list, if I select one of the resolutions that are listed for example 640 x 420 it is in 15khz.

Any idea why 640 x 480 isn't showing? Any suggestions would be great please!!!

Got it working - catalyst 11.3 works :D
