I successfully installed drivers to run the Nvidia 750 Ti graphics card in my desktop. Ubuntu ran perfectly for a short time after that. Then, the update manager prompted me to install some updates. I did so and rebooted. After that, when I try to login the screen blinks and goes back to login. I have tried several other guides which solve similar problems but none of them have helped.
I am dual booting Windows 8 and Ubuntu 14.04.

This happens when you install Nvidia drivers using a .run file, downloaded from Nvidia site. This a wrong way to install drivers. After each kernel update you will have to install them again using console, because GUI won't start. Now you can fix it by going to console by pressing Ctrl+Alt+F1. Then login there and run
Then reboot.
If this does not work, then you need to uninstall the driver. You can look HERE for instructions.
