The computer crashes when the video site (YouTube, among others.), openSUSE Linux 11.3 (Final)

The computer crashes when the video site (YouTube, among others.) Stay open full screen (in low resolution, for example: https://www.youtube.com/watch?v=(http://www.opensuse-guide.org/codecs.php), that I can watch videos and other things on your computer.

See my Hardware below:
