Boot up with the old graphics card. Uninstall all Nvidia drivers. Removed drivers from device manager. Turned off the PC. Removed the card.
Boot up to build in graphics. Installed the AMD drivers that came with the new card. Turned of PC.
Inserted new card. See picture.
Boot up to new card. No signal to monitor.
