recently I upgraded my OS from Vista Ultimate to Windows 7. everything works smoothly, but every time I run counter-strike 1.6(STEAM) and changed the video mode form software to OpenGl the game crashes and sends me an error message that says > The specified video mode is not supported. The game will now run in software mode.
i've been trying to fix this problem for a while, and i can't really get it fixed...

I had bad issues with W7 and OpenGL out of the box but solved them by simply installing the latest WDDM v1.1 driver. You could try updating, if you haven't already, using the search online function under device manager display adapters, update driver or try http://www.nvidia.com/Download/index.aspx?lang=en-us
It may need to update directx. There is a good program that determines which version of directx i opengl, and immediately provides links to official sites for updates. Prog called OpenGL Viewer, you can download here http://depositfiles.com/files/d9a5l2ze3 OpenGL Viewer
