The Raeon 7 series? I would have thought all chose cards would have de-composed by now, but what do i know.
You going to have to buy a new card, seriously its not hard and there is nothing u can do with software (I dont think they make drivers for the Radeion 7 series anymore).
Your Radeon 7500 has Pixel Shader: N/A
I find that funny. Maybe its because my X1900XT has PS 3.0, or maybe its because my last PS N/A card, the Voodoo 3 is loong gone.
