I also tried loading the winvista 64 bit drivers for my NVIDIA nForce 570 SLI chipset. I put them on a USB thumbdrive and selected 'Load Drivers' during the beginning of the Vista install. Still no luck. Now it hangs at 13% expanding files.

My next step is exchanging my motherboard for a new one with a different chipset. I could have a faulty board or the board may not actually be compatible with Win Vista 64 bit.
