Im having troubles with the listed device - i've downloaded all the drivers available from the Gigabyte website and they have had no affect so far.
I have also lost my SATA drives, in a rather mysterious twist.
I have been unable to get this driver issue solved before, but it wasnt causing any clear problems, so i left it alone.
The power went out today, and when it came back on, low and behold, we have the current situation.
Im using a Gigabyte K8NS Ultra 939
Thanks : )
