I am not sure about your board being one of the problem boards, but I know that Via chipsets and ATI AGP radeon cards with AMD processors don't get along very well. This is not the case with all motherboards but many have the problem. Asus boards are famous for it. This may be something you may want to investigate a litte. I ran into that problem using maya with my ATI card. I no longer have the problem because I am now using an NVidia based card. This may help you in your search for a solution.
