I'm actually fund out solution for myself. I just went on lenovo support site (my pc is lenovo z500), this recommended me guy on Nvidia online support, that manufacturers can have resources what I need. I checked drivers I downloaded few an installed one by one. One of them was upgrade for bios for my PC and that one helped. I installed it and everything seems working fine ofc graphic is finaly not hidden.
My recommendation is, go on your manufacturers site chceck drivers what you (probably som for bios will be right one) think, that can help you try it and hope. But I think general problem is somwehere in bios, too hard found and fix it for normal people. (sorry If I did too many mistakes but my english is not best)
