Fix 3d prophet kyro 4000XT tv out

My video card (3d prophet kyro 4000XT tv out) has suddenly decided to allow direct3d to die. told me to install the new driver, i downloaded this, but when i run it, it says that ive still got the old driver installed. ill be damned if i can find where it is, ive checked add/remove programs and device manager. How can i remove the old drivers so i can install the new ones?

My computer is:
P4 1.8ghz
directx 9.0c

Try remove hardware…and it should prompt you to remove drivers. Boot, and it should find your graphics card and prompt to install existing drivers or your new ones…
