Try backtracking to DX9.0b , if that doesnt work backtrack ati drivers try it with older ati drivers + DX 9.0b then with DX9.0c, it might be something to do with the card drivers (I got an ATi 9800) although it doesnt do that for me. BTW you might want to check that your card isnt corrupt/burnt or been knocked about and that all the wires are fully in(sounds stupid but many people have done it)
