My Nvidia Geforce GTX 460 1gb keeps crashing my whole system while playing 3d games. I installed the latest drivers and nothing has been fixed. Is this a problem with all nvidia drivers and there is something your meant to disable?
The only thing I can provide for possible debugging is that when playing HD videos through VLC or SMPlayer(System can also crash while playing in SMPlayer) the video lags and the sound is prickly but while playing the same videos in MPlayer it works fine.
SMPlayer uses MPlayer to play its videos so I can only think its a setting that's causing all this to happen. Even when I play a Video through SMPlayer but have the setting to use a MPlayer window I get the same result.
I have Ubuntu 12.04 by the way.
