Try to install the drivers but it comes up with 'the realtek controller was not found. If deep sleep mode is enabled pkease plug the cable'

Desktop machine? Did you disable the onboard controller? Does the new controller show up in the device manager with an exclamation or not at all. It would be very helpful if you provide more information on your motherboard/computer and the Realtek controller that you added.
