331.40 drivers problem, GF 460M Notebook MSI GT680

I have a problem. Turbo boost in my notebook is not working with every drivers since 320.49 whql. And now I can’t change brightness in my notebook on 331.40, I mean I can change it in nvidia panel but can’t change it in power options and by button Fn + arrow up(brightness up)/arrow down(bright. down)

Please fix it :( Thanks, and sorry if I wrote it in wrong section.

Have a good day.

Ps. As I noticed, Turbo boost needs application MSI VGA Overclock. To fix it I need to run this application as administrator.
