I would have reinstalled the whole OS3.9 setup, and installed all the right drivers for your cards within it...and an advice..Look out for the latest Boing Bag Upgrade for OS3.9, the Boing Bag 2...It should fix a bunch of bugs available at the original OS3.9-setup.
Hope you will work it out at the end..Read every information that pops up under the reinstallment very carefully...
