Open GL failure in cs 1.6 appcrash

Hi,
Im having trouble getting openGL to work in cs 1.6
it works in d3d and software but i need it to run in openGL
Im using a laptop asus n53s
in device manager it says 2 display adapters
INTEL HD graphics family and NVIDIA Geforce gt 540m
anyone know how to fix this?
need step by step instructions and where to go cause im not good with computers
thanks!

CS 1.6 is not a high end game and it can run on Intel as well as NVIDIA. There are chances that the game is opening with Intel and the OpenGL support may not be there .Found a link in NVIDIA KB's and may help.

How do I customize Optimus profiles and settings?
