If this is a previously created installation, make sure that any older drivers for any other video cards are removed before installing the new card. I suggest that you do this in Safe Mode.
If this is a new installation, check and make sure that the Display is set for PCI mode in the BIOS, instead of AGP.
It's possible that you may have to install the operating system with an older card, and then add the new card after installing the Standard VGA Adapter. Then add the ATI drivers.
Again, if this is a previous installation, switch to a Standard VGA Adapter before adding the card and drivers.
Note: If you have an integrated display adapter built into your mainboard, disable this in the BIOS immediately after adding the card, (and before booting into Windows) or you'll experience a device conflict. Be sure to save all changes in the BIOS.
