Guys I'm stuck!

I love this board nice lay out but...

I'm not able to do a clean Win7-64 install. When I run the installer it will ask to load SATA AHCI drivers. I have downloaded all the new drivers from this site and copied them into a CD but still nothing no luck.

I get this error:

The Intel PCH SATA AHCI controller iaAHCI.inf device driver could not be installed. Contact your vendor.

Any clues guys?
