Having 3 monitors in Windows 7

I just upgraded my system from xp to Windows 7 and now I can only used 1 video card.  I have a radeon 1600x PCI express that runs 2 monitors along with an older PCI monitor card.  If I put one or the other, the card works just fine, so the drivers are good, but when I install them both together, I get a Code 10 on the PCI card.   I'm assuming there's a shared resource that I need to resolve, but I'm new to Win7 and not sure how to proceed?

Two different graphics card cannot work in windows 7 environment.
That's  the new windows 7 video architecture .

If you mobo supports cross  fire then you can install multiple cards but  ATI graphics card should be identical.

Please check these articles.

It's a Dell OC27W with an IntelQ45 Chipset.  

I don't know how to check to see if they are fighting?

Well, I've found you don't have to have identical video cards. Both cards must be from the same vendor. You may need to upgrade the  'older' card to another ATI one.

You know, I'm getting tired of Microsoft telling me what I will and will not like.  If I want to put 2 video cards in my system and it gives me a blue screen or "forces me to reboot" {boo hoo} then that's my choice!  Even though I am surprised about how well win7 is working, I'm sick of every time something new comes out, I loose flexibility!!
