I have a GeForce3 (Cardex/Gainward) running on an Asus A7M with a 1.4 T-bird and the damn thing locks up with the XP drivers while running 3D apps (3DMark, Shogun, etc.) but when it finishes it rates great. When I use the manufacturer's drivers it doesn't lock up but gets horrible scores...anyone know a resolution to this? I've tried AGP aperature adjustments, video shadowing adjustments, newest BIOS, newest drivers for EVERYTHING..., disabling ACPI...what the heck is going on?! Help Please!!!
