some nvidia demos won't work with my 6800

[x1600c]

GAAAAH when I try to run some demos with my XFX6800 vanilla the program changes the resolution, begins to play some music, but it never loads. instead it closes saying that an error has occured.This happens on the nalu, and "last chance gas" demo. Its not a software problem (as it still happens after I reinstall XP). how can I resolve this?

what driver version are you using?

I had the same problem with a 6800 Ultra. Uninstall all of your demos and then your drivers. After that use a driver cleaner, and reinstall the demos, they should now work.

and when I uninstall my drivers, what version do you recommend?
