Solving for VGA card problem

Install or Reinstall nvidia Driver
You can download the driver from the Nvidia site.
Then you do install as following steps.

If you've enabled the restricted driver make sure you disable/deactivate it before doing the following.

1) Press Ctrl + Alt + F1. This will open up a terminal. You have to login with your username and password.

2) Then you have to stop Gnome by doing: sudo /etc/init.d/gdm stop
If it asks you for your password enter it again.

3) Then change to the folder where the installation file is stored and
run it by doing:

sudo ./NVIDIA-180...............run
(NVIDIA-180.........run is the name of the install file - pressing
tab will help you there)

4) The installer will start. If it asks you whether you want to download a kernel interface it's probably best to say no (never worked for me). If you choose not to it will then ask whether you want to compile a new kernel interface. Say yes. Then it starts installing. After it finishes it will ask whether you want to run nvidia-xconfig to configure xorg.conf . SAY YES. Installation complete.

5) You can start gnome again by running:

sudo /etc/init.d/gdm start

So that's it installation complete and it should be working well.
