Seems to be the graphics card driver issue. I had a similar one and got it fixed, you can refer to that here

Generally you should use the drivers from the official Ubuntu repositories. Because you are having problems, using the latest drivers might be better. Install the latest official stable NVIDIA drivers for the GEFORCE GTX 740M.

First uninstall the currently installed NVIDIA drivers. Boot the computer, when the GRUB menu appears ...

Highlight the Ubuntu menu entry and press the E key. Add nouveau.modeset=0 to the end of the linux line. Press F10 to boot the Ubuntu operating system.

When the login screen appears press Ctrl+Alt+F1. Enter your user name and the password, then execute :

sudo apt-get purge nvidia*  
sudo reboot

Now install the latest official stable NVIDIA drivers. Boot the computer, when the GRUB menu appears ...

Highlight the Ubuntu menu entry and press the E key. Add nouveau.modeset=0 to the end of the linux line. Press F10 to boot the Ubuntu operating system.

When the login screen appears press Ctrl+Alt+F1. Enter your user name and the password, then execute :

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-361
sudo reboot

Note : Maybe it is explicitly necessary to select the NVIDIA adapter in BIOS. When you want to use drivers 361, adding the PPA is not necessary. In this case the terminal commands you have to perform are these :

sudo apt-get update
sudo apt-get install nvidia-361
sudo reboot

In case you have installed the nvidia driver from their site(*run) then uninstall it as per that instructions.
