OK, just a FYI. Since your previous post on November 12, 2009 another person was having some difficulty with an Abit IP35 series board.
I was looking at the Abit site, and noticed their BIOS's had not been updated since July 2008. Investigating further I found out that Abit had either been sold to or merged with another company and ceased building motherboards in 2008. From what I read they were intending to support the boards they had previously built for 3 years from the time of manufacture.
The latest and last BIOS update for your board with a Q6600 was version 17. If your current version is less than 17 a BIOS update may be in order.
I hesitate to suggest a BIOS update, however if you don't have version 17 it would be necessary to update to version 17 for the Q6600 to be supported. I would be somewhat nervous about this since if Abit is no longer building boards, I don't know what kind of actual support is available.
