i have a dimension 5150 everything is stock and i just got a new video card, its a XFX Geforce 7600 GT 256 mb PCI x16 and i just put it in and now am going to install the new drivers but when i put the cd and click "windows drivers" it starts to install then this warning menu comes up and it says:

 

the software your are installing for this hardware:
