VGA controller for compaq nx9010

I recently formatted and reload the operating system of my latop, but since then the display part does not covers the whole screen and the screen flickers when i drag objects or items or scroll down or up, i tried trouble shooting and got to know that the VGA controller driver is not installed, please kindly send me a copy of this driver or the link that i can download it from except HP web site as the link in the web page is not working properly in my country, my email is once again adeyemi.s@hotmail.com
