You may try the 6071 drivers. Apparently, the latest drivers have been causing problems for some. Also... with ATi cards the install order is extremely important.

1) clean install of Windows
2) SiS AGP driver (up to version 1.10 now)
3) DX 8.1 (unless you are using XP because it has 8.1 already)
4) ATi drivers
