The RivaTuner was built for Nvidia cards that's why. It wont work on ATI.
As for the issue it looks like a video or setup issue.
1.) download the newest ATI drivers from their web site. Uninstall the current drivers you have goto the device manager and delete the card reboot The machine and then run the install for the newest drivers. Test it.
2.) uninstall CS1.6 then run defrag
3.) install the game again not using the auto run find the setup.exe and right click it and set it as "Run as Administrator" then install.
4.) run defrag again. then test.
5.) if it still does it then set to run as administrator and try again.
Let me know if it works for you.
Also was this a clean install or an upgrade?
