As far as the Gigabyte goes these are the settings i usually use

On Chip Sata Controller: Enabled

On Chip Sata Type: Native IDE

On Chip Sata port: IDE or As sata type

I hope this helps..

Just went thru some of the forums online and found it could easily be a RAM issue.. since AHCI drivers are built into vista and shouldnt cause any problem...

Vista have native support for ACHI. ACHI (Advanced Host Controller Interface) is more advanced than Native IDE or Lagacy. If your HDD have advanced features like NCQ, you should select ACHI. AHCI is supposed to be better ( though there wont be any noticeable changes in system performance)

If you select Native IDE, your HDD will just emulate IDE over a Sata cable.

Also, once you have selected a setting, if you want to change that again, you have to reinstall the OS.
