I can't get crossfire enabled on my card, its a Sapphire 4850x2 1GB. It used to work, but cant get it to turn on it W7 or Vista with any drivers. It has quad DVI and only the top 2 work the bottom don't seem to do anything. Not sure what could have killed it...?

Anyone have any ideas? In the drivers it says 4850x2 PCI-E 16X...etc,etc Cat 9.6

I can't figure it out will probably have to RMA again. I hate sapphire!
