I get this error sometimes when I am level designing in UT3, or when playing a steam powered game like team fortress or counter strike. My monitor will go blank, then come back on in a few seconds with the error "nvidia driver has stopped responding and has recovered" in the system tray. It's very annoying and I'd like to know what causes it! I've searched all over google but to no avail, I'm hoping someone here could shed some light on the situation. My system is NOT overclocked, plenty cooled since its an antec skeleton case, I've tried un-installing the nvidia drivers completley and installing new ones, it still happens. I don't know what to do! I'm running windows 7 64 bit.
