I'll assume for the time being you are referring to the game 'Counter Strike'.
The snipping tool is unusable (to an extent) while playing the game, its usually only good for getting small pictures or images of certain areas on the screen.
As to the main problem, I am not sure what would cause the black screen, aside from perhaps try updating your graphic card drivers?
