problems with display 9800se

been trying all sorts of drivers with this.. closest i've got is the Omega drivers for 9800se.. but i still have a problem with faint blue lines going vertically and this really does show in game..any idea of another driver i could use to clear this? ( have tried ATI catalyst)

shows on image here.
