RE: AFP graphics problem
Ok. The first question would be, have you disabled the onboard graphics in the setup/BIOS? Also, is the card you are installing an AGP or PCIexpress? You also say that the install disk is giving you this message. I assume this is the disk that came with your new card? You're getting the screen to come up from the new card when you get this message? Is the operating system booting up normally or at a minimum resolution? If you are able to boot up and have a broadband connection, you may want to go to PNY's site or Nvidea's and download the latest drivers for your card and see if that will run the install correctly.
Again, the more info, the better chance I or someone else reading this thread can help you get up and running. Good luck.
