Pc Game Amnesia: The Dark Descent wont run, what do i do? Intel(R)Graphics Media Accelerator Driver?

Im trying to run the demo that i downloaded from the original website, so that isnt the problem. It is the graphic driver i have that is below the minimum requirements to run the game so i dont know what to do and i dont really understand graphic drivers. The game crashes before starting and i am using an Intel(R)Graphics Media Accelerator Driver
