Hi all! Just arrived here and here I'm because of big trouble

I've installed today a second X1950 Pro card. The first one is an Asus EAX X1950 pro, the second one the same card by ATI. I've uninstalled the old Catalyst (7.2)than I have rebooted and in Device manager I've found the 2 X1950 pro. Then I've reinstalled the Catalyst (7.10) e newly I rebooted. I DON'T WANT A CROSSFIRE configuration, I only need to have on the first card my 30" monitor and on the second card the two 19" monitors.
In Catalyst control panel I see now
4 icons (1-3-2-4 displays)but I see only one card listed with a monitor. If I enable the monitor (3) in the second card, I can see for a while the desktop in the second monitor, but in a couple of minute all disappear, I
see line e points and then Vista (ultimate X64)
crashes. (I link some screen to better explain)
When I've rebooted I've seen
this warning
and this description:

I've no option to uninstall the catalyst for reinstalling newly, there are no uninstall application in 7.10.
If I don't attach any monitor (display) on the second card, Vista works fine, only if I enable the monitor on the second card Vista crashes.
I've tried
with and without the two crossfire bridge molex: same effect.
I don't need crossfire but only to have 1 30" display on the first card and on the second card Other display.
I think that the problem is in the Catalyst driver because it's in that control center that I don't see the TWO card listed, while Vista device manager has both.
So can i have to do?
I know that my english it's bad.... sorry about that, but here where I live I don't know any one and the only store here is a Future shop.......
I have assembled my pc by myself with no problem but with this situation I don't know What I can try.
Please Help me, poor woman in big trouble!!!

THANKS!
