If you have a Socket 939 nForce3 motherboard and want to run Aero you may do so in one of the following configurations.
Any AMD64 single core CPU and any Aero Capable AGP Video card.
If you want to run Aero and have a dual core CPU, then you MUST RUN an Aero capable GeForce card.
Running a Dual Core CPU on nForce3 with a non NVIDIA Graphics Card causes the graphics card to throw a Code 43 error.
Nothing like NVIDIA waiting until the last minute before they came clean.
Both SiS and ULi AGP chipsets had the same post Vista RTM issue and have subsequently released fixes. So if you want to run a dual core 939 CPU and an ATI Graphics card, you'll have to change platforms.

I understand the difficulties that you are currently facing. However, I would like to inform you that nforce3 is end of life product so we don't have any supported drivers for Windows Vista Operating System.
