After deinstalling and re-installing graphics drivers i don't know a solution any more.Here is the problem.
So after i go to configure the switchable graphics for a game to high-performance,the second i go in the game the screen is black.
This only happens when i configure it to high-performance.
Does anyone know the solution...
