Guild Wars 2

Yo tengo el mismo problema con una Nvidia GTX580. Cuando le pica, el monitor se queda como si hubiese apagado el ordenador, y a los 5-7 segundos se vuelve a encender.
Tengo la versión 306.23 de Nvidia, la última y recomendada por el juego y no me lo hace con nada mas que con el GW2. Os dejo las especificaciones del DXdiag:
