1. you need file called
ati3duag.dll
and
ati3d1ag.dll(if u have this)
but first solve problem
you get ati3duag.dll from last working driver (7.8;7.x) in system32 folder
and copy it on the desktop.
2 now uninstall your driver & clean your compter with Driver Cleaner , this permanently remove old driver files.
3 now u can install new catalyst 7.10 and reboot
4.finaly after this reboot again your computer , but this time in safe mode (F

and copy ati3duag.dll in your desktop to system32 folder (overvrite existing ati3duag.dll) .Now reboot and try your games !!
IMPORTANT: Keep the saved files so that your next ATI driver if the problem still exists, you half the effort you can save! ! !
cuz i use ati3duag.dll(from cat7.3) with catalyst 7.10 and all works fine!
Now i can play enemy territory quake wars with good fps and all other games
