Lu(ky - So your gonna get a replacement instead of a refund and new motherboard? Its a tough call because there is a good chance alot of these minor issues we're all having will get sorted sooner or later? On a different note I just installed my QX9770 and it booted right up with no issues at all! Granted I'm just running it stock but at least I didn't have any issues with the board recognizing it. It took me a while to get it installed becuase the QX9770 has no IHS if you can believe that (must be very careful installing waterblock so neither of the cores crack)!

Leeghoofd - If I understand correctly your not able to install Vista because you get errors during the install (errors about copying files)? But this same board worked fine with pre-installed OS before? I'm sorry that I didn't understand fully
