If your onboard graphics is still active, your computer cannot recognize the new graphics card.



And merely deleting your onboard graphics' drivers in Device Manager will NOT disable it. It merely deletes the driver and forces Windows to ask you to reinstall it.|||1st - Turn off your computer and take out the plug.



2nd -Take out the video card.



3rd - Boot your computer and the VGA standard will take over. Big Screen



4th - Load the video card drivers into your machine.



5th - Shut down and turn off your computer and unplug the cord.



6th - Put in the new video card



7th - Plug in your machine and then turn it on.



8th - Your new video card should be recognized, the drivers loaded and your screen returned.
