There's not quite enough information here to identify your motherboard, but you should make sure there aren't any BIOS upgrades available for it, as those might help resolve this level of issue.

Check your BIOS config for the disks carefully, and try adjusting the options you have.  In particular, try choosing LBA mode rather than auto or CHS, and try to toggle through "ACPI (or SATA mode)" vs. "IDE (or PATA compatibility)" vs. "enhanced (often meaning some form of BIOS RAID is enabled)" and see whether any of them work.

If that doesn't do the trick, you could wander through your BIOS menus, and disable all of the non-essential stuff like parallel & serial ports, second NIC, or anything else which is not needed, and see whether that does any good...but that's getting into stuff which is less likely to make a difference.
