Thanks to you all who helped me out of this weird problem, but I should tell you something now - it's quite embarrassing :) I spent couple of hours to read several forums where nVidia users got same kind of problem that me had. And someone said that "have you checked that external power supply is attached correctly to your card?". In that moment I stop to think: "...external power supply..." and check that as soon as possible after work. Guess what was the answer? :D No. I haven't attach the external power supply cord to the card :) After that, I did install nVidia's own drivers and reboot. Heureca! nVidia logo shows and X started and 3D screensavers runs approximately 500-700fps :) I was laughing so loud and long time :D LOL On that moment I feel myself so stupid that think four times to writing here and tell my story at Battle of nVidia :) But modprobe problem is still open. It throws an error at line, where is defined the network interface (as I'd said before on my messages) But thanks for all - nVidia rules! :) So happy, Jarkko Elfving
