Crossfire Crashes

I've just installed the second Asus 5850 in crossfire setup, got 2x8 pin plugs & 2x 6 pin plugs in so that's ok checked everything 3 times all seems fine till I boot up and after 20-30 secs it crashes.
Anyone got any ideas what i'm doing\got wrong,
my heads blank but that's normal


I'm getting really pee'd off now, I have ripped my rig to bits(bare drive and gpu's) and still I can't get cards to work in crossfire.
I've run cards on their own rig works no crashes,
both installed no crossfire link cable rig works no crashes,
tried wiping ati drivers with drive sweeper install again crashes,
tried different link cables it crashes,
different PCIe slots xfire link cable in crashes,
Now just reinstalled ati drivers and don't have CCC rig working with both cards in but no xfire cable link, as soon as I connect cards together with link cable it will boot to windows ok but but it either crashes after 30-40 seconds or if xfire not enabled in CCC as soon as I enable it crashes BSOD.
What is going on this is a nightmare.
2 crash dump pics.

Hey, im having the same problem i looked it up and its the Catalyst driver itsself. does your screen freeze or bsod? cause thats it i was using my setup 2 6770's in crossfire went to overclock it and the ccc driver crashed and it keep freezing my computer so i started my computer up and before it culd load anything i loaded up the task manager and found the ccc.exe and ended the process.. i then went and uninstalled the catalyst control center and it works fine.. i hope im not to late and spread the word to AMD can find out whats wrong
