Nvidia Linux 64 bit driver installation on Fujitsu SH561 with CentOS 6

My office give me a new Fujitsu SH561 laptop. The preinstallation OS is Windows 7 profession. So I take the free HD space to make CentOS 6 installation. To build a twin system laptop.

But when the CentOS is installed, the display driver is set by the CentOS official's. The resolution is only 800x600 and make me bad view. So, I decide to take the Nvidia official drivers.

First, to go the Nvidia official site and the driver download page.
http://www.nvidia.com/Download/index.aspx?lang=en-us
Choosing your display card series,ex. GeForce 500M, card name, mine GT520M, operation system, mine Linux 64 bit, and the language.

Second, you need to close the GUI level 5 and run level 3 on the text mode. System calls close X server.
