PCi-express Card problem

[bigjim]

I have a Ecs geforce7050m-m with a nvidia 7050 and i added a Pci-e x16 Nvidia 7200gs with 256 mb. and when i installed it and configured all of the bios crap and when i went to boot it up i got the stupid "You need to restart your computer" thing and when i removed the card i would boot up using just the onboard card i would get to a functional destop and would get a kernel panic after i clicked shut down.

can someone pleaase point me in the right direction for getting the dumb thing working--or tell me how to make it work

Thank You for any information
