I recently installed a ASUS GTX560 graphics card in my desktop and out of the box everything was working fine. I decided to check for available updates and one of the suggested ones was the most current Nvidia driver. After Instillation, I rebooted and now the OS makes it to one screen past the boot loader. It is a screen with multiple tests being run and a few of the answers are "no". I tried booting in recovery and safe mode and removing the Nvidia driver update through the terminal but still to no avail. I don't want to have to do a clean install of ubuntu to get my system back because I have 3 years worth of files on the disk. I feel very lost after spending hours on the forums and I would really appreciate any help.
