ECS K7S5A, Athlon, Stealth III S540 X

I have an ECS Motherboard K7S5A, Athlon 1.4 GHz processor, and a Diamond Stealth III S540 Xtreme AGP. My OS is Win 2000 Pro. Everytime I load the AGP patches from AMD, ECS or SIS (735 chipset) and Diamond’s AGP drivers, Windows locks up in the Windows initial screen. Is there an exact order and/or a certain set of drivers I need to download.
