Did you reinstall windows drivers????
I had some trouble with my ati card untill i did the following...
booted from cd..
renamed windows directory..
installed windows..
installed card drivers..
got upgrades..
and all trouble stopped!
Thought .. perhaps the old drivers for my old card were interfering some how with the new drivers for my new card?
I have a slower system then yours but now it seems it's working faster then yours? a 500 athlon, 98se, 9000pro, but gettin some good fps...
Don't know for sure but FPS is up and everything now works as it should!!!!
Hope this helps!
