This happened on my acer aspire 4920g notebook. It has ati mobility 2400xt 256mb. I have downloaded the latest driver catalyst 8.10. but after i modded it with the mobility modder and install the driver, the device manager recognized the driver as catalyst 8.5. and the fps performance goes down on my games. can somebody tell me how to fix this?

Vista or XP?

Regardless, do this:
1) Turn off UAC (Vista only)
2) Completely remove your existing drivers, using the ATI Uninstall Utility under Add/Remove Programs (XP) or Programs & Features (Vista), reboot if/when prompted
3) Check C:\WINDOWS\INF\OEM*.INF for ATI entries. Some factory-installed drivers are 'sticky' like this
4) Reinstall your modded drivers (no need to re-mod, just run C:\ATI\SUPPORT\<driver version>\setup.exe. Overwrite all files if prompted.)

Let us know how you make out.

I have the same problem, only difference is that I have an Acer TravelMate with Windows XT Professional, 2 GB RAM and Mobility Radeon HD 2400 XT (512 MB). I did all the steps you described (deinstalling old drivers, restart, install new drivers by using Mobility Modder.NET, restart, finish) but my game performance is worse then it was with the old drivers.
My question is: What exactly do you mean with point 3? Do I have to delete them before I install the new drivers? What do you mean with the 'sticky' ones?

Yes.

Windows scans C:\WINDOWS\INF whenever it detects new hardware and needs to install a driver. Many OEMs load a custom INF into this directory, and their associated uninstallers do not remove this. Therefore you're stuck in a loop of uninstall -> reboot -> redetect -> reinstall stock driver, in many instances without giving you a chance to cancel the driver install.

You don't want to remove all the .infs from this directory, just the ones that a) are named OEM##.inf (where ## is a number) and b) contain ATI video adapter infos. Removing these properly forces the Add Hardware Wizard to appear with the subsequent removal of the device.
