Hello, I have had a Radeon 5850 Crossfire setup for a few months now. One day the drivers stopped finding the second card. I have a Gigabyte P67A ud4 B3 motherboard. After trying to find the error i tried to change the cards around. Same result only the card in the upper PCIe port was found. It does not look like there is anything wrong with the second port but it seems like it might be broken.

What i want to ask is if anyone has any suggestions or ideas on how to fix my problem before i replace my motherboard?
