You might try a rerun of Intel chipset install pak 9.3.XXXX before anything since with various bios updates it may need to detect a newer OROM, And I would do a full cmos reset with PSU unplugged even before that.

Windows 7 Ultimate (圆4) Service Pack 1 (build 7601) This INF is just a backup in case step 1 does not do the trick.
