Crossfire problems/question

Been trying to setup Crossfire with a pair of Sapphire 1950Pros on an ECS KA3 MVP. Both cards work fine independently, but once both cards are installed, and it doesn't matter which card is where, I can not get any video signal out of the second card.

I thought that you had the option to run two cards on a Crossfire motherboard independently, so that you can run four monitors, am I right? And shouldn't I also be getting some type of video output from the second card during boot up will the bios is loading??

So opinions, I have two independently working graphics cards that will not function at the same time when I put them in my motherboard. Where should I starting replacing parts first, the motherboard, or the graphics cards.
