Sorry to have missed your post so long!! I have been gone for a few weeks, and likely none of the guys who help out in the Gigabyte section noticed your post here.

I would advise a clean install of your OS once you get going though, it may not be a must but it is advised especially coming from netburst to core based CPU's.

Did you try BIOS F9? Could just be the Beta BIOS you are using? I would try F9 and load optimized and save/apply/reboot back to the BIOS and then see if all is well. If it is working then I would go ahead with a clean install, be sure you have your SATA Settings setup properly and your boot disk order with your OS Drive at the top of the list
