Buenas, puedes probar a diagnosticar el estado de la tarjeta con OCCT, aunque desconozco si no utilizar los controladores afecta al análisis (creo que no)
http://www.ocbase.com/Aquí comentan el truco de utilizar un controlador muy anterior, por ejemplo de hace uno, dos o tres años. Puedes utilizar
Driver Sweeper para asegurarte de haber desinstalado por completo el controlador precedente.

http://www.xatakawindows.com/bienvenido ... -windows-8BEFORE YOU DO ANYTHING USE WINDOWS UPDATE TO FULLY UPDATE YOUR MACHINE, THIS IS IMPORTANT.
1. Use GeForce Experience to download current Nvidia driver then select "Clean Install", this will fail however it will succeed in resetting the device to being an unknown display.
2. Restart.
3. Go into the "Device Manager" and right click the display device and choose update driver. Browse manually to the Nvidia folder on your machine where the updated proper driver has been installed and select it. This may or may not work but it should at least identify the device as a discreet graphics card, in my case GeForce GTX 760.
4. If that did fail try right clicking and letting Windows find the driver, hopefully it will install driver version 331 which is the Nvidia driver that came out around the same time as BF4. If this works, and it took me a few tries to get it to, 5. Restart.
6. Go back to "Device Manager" and right click the now functional GeForce graphics card and choose update driver, browse to the current version that is installed under the Nvidia folder tree in your local drive. Install.
7. If this worked, Restart.
