So I just put together a haswell build with windows 7, I am using haswells integrated graphics and i just downloaded steam and halflife2 + episode 1, and when I double click to play the screen flashes like the game is about to launch but then it just stays on the desktop and nothing else happens? Anyone have any idea why?

thanks
