ATI Driver issue

[QueenElizabeth]

Hiya,

I'm a complete nj00b so bear with me.

I installed the game and had the usual 'Failed to initialise renderer' issue.
So I followed the program:
- Got the Windows 2003 Service Pack 2
- Ran the Cat Uninstaller from ATI
- Rebooted
- Downloaded 5-10-xp-2k driver from ATI

Weird thing is, instead of installing the 5.10 driver it stops at the red ATI screen and says:

'Setup was unable to find components that can be installed on current hardware or software configuration'.

I did DxDiag and got this..

Civ IV still doesn't run, obviously, and I seem to have uninstalled my drivers without installing any new ones..

Help!

Thanks
