I forgot almost all of my dreams after waking up focusing on trying to solve one of the most frustrating & confusing computer problems that I have faced in a while, I have tried to figure it out for two days now, but I still have not fixed it yet.
The other day I experimented with installing an older Nvidia graphics driver for Ubuntu to see if it would fix my problem with some online videos playing choppy & embedded YouTube videos on WordPress.com playing choppy; but Ubuntu would not boot after restarting my computer, I can not use any of the terminals to try to remove the Nvidia drivers, I can not boot from any of my DVD-Rs or DVD-RWs or my memory card that I have set as a bootable Ubuntu installation device & I even tried to make new bootable devices from the Windows side & the Ubuntu side on my other computer, and so I can not re-install Ubuntu or fix it or delete it or anything.
