My computer wont let me play one game, how can i fix?

So I recently got a new laptop (Satellite L655) and I have been able to play alot of games from steam so far like Terraria, Left 4 Dead 2, TF2, and Medal of honor (the newest one). but I had bought a game called amnesia off of steam and when ever I try to play it, it says there is a fatal error renderer #0. So I dont know if its my graphics card or my ram, but if it is my graphics card how can I get one?
