My system always crashes while booting [related to Nvidia driver]

As I mentioned in Q, I am facing a problem while booting. Previously I used elementary without problem, but recently I changed to Ubuntu 14.04, I am facing these issues like:

  1. Background crash (i can't get exact screenshot, but that is similar to this image)
  2. Browsers crashes (firefox and google-chrome newest version)

Sometime i get : loop login infinitive
My computer detail:

My graphic driver is : Nvidia 352.55.
Please let me know, if I have to produce more information.
The proble resolves after several reboots.
After

sudo apt-get purge nvidia*
sudo reboot
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-355
sudo reboot

My system becomes like: enter image description here Can't open Dash, Launcher, Shortcut like Alt + Ctrl + T .
Lucky i have Folder at my desktop so i can open via Mouse click.
After fix Ubuntu lost Dash, Launcher, Shortcut Browsers still crashing Browsers still crashing :D
