For the sake of everything that is, was, will be or might be sacred, instead of this wall of text, post:
- Nvidia driver version number.
- Kernel version number (and better the output of uname -a).
- Types of failures (graphics distortion, uneven video playback speed, slowdown, high CPU load, graphics or full computer lockup, kernel panic if kernel or logs are collected).
- Software used.
Right, Nvidia recommendations are not very useful and their collections scripts are often not accessible at the time of failure. Nevertheless, please post something that qualifies as a bug report.
