Hola Pablock.
Lo preguntarás pq me imagino que te has encontrado con este mensaje en la FAQ de NVidia (

You will need to contact your graphics card manufacturer for the latest custom BIOS for your graphics card. NVIDIA does not provide a reference BIOS for NVIDIA-based graphics cards because flashing a graphics card with an incompatible BIOS can permanently damage your graphics card. Instead, you should contact your graphics card manufacturer for a custom BIOS that has already been tested and qualified to run without any problems. If your graphics card came bundled with your PC, then you will need to contact your PC manufacturer. In most cases, a BIOS upgrade is not needed. Most issues are resolved through driver updates and not video BIOS updates"
La verdad es que no tengo respuesta ya que tampoco conozco ninguna pagina que recopile BIOS de tarjetas de video (¿existirá?).
Igual alguien te puede ayudar si nos expones el problema de tu ??
Un saludo.
