Hello guys. I have the exact same problem, only with Asus A7n8x mainbord (nforce chipset drivers) I have geforce4ti4600 and installed newest drivers but it stands its in PCI modus in properties.. If I install the unified driver package (mainbord drivers) my machine just hangs up.. So Im wondering if anyone know how I can just install the agp drivers, I have them on my computer, but dont know how to install them. (Gart drivers) Hoping you guys can help me!
