The game started with the graphical process

The problem is that games don't want to play the nvidia graphics card. First black screen (the game decides on what map I play) nvidia crashes if if not then not. Was current-hedgehog problem but the game start in a window if nvidia crashes if not then no, went to settings put on full screen, left and a miracle I went with nvidia. With another game current-hedgehog setup did not help. Please help.
