One day I tried to run my Modern Warfare 3 and it gave me a blank screen so I rebooted pc and try Saints Row: the Third, it also gave me a blank screen. I got Crysis 2 to work and dead island but in dead island if I try send invites to friends the game stops responding. I have tried a lot of thing and even reinstalled steam. Nothing has worked. Now all games are not working.
I have done both but it still doesn't work If I verify my games most of them need a few downloads but then when I run them they crash and I have to re-download the same thing. I have worked out that its something to do with windows but my steam drive works fine on my friends alienware. I will mostly likely reformat windows and reinstall steam to an internal drive if I get a 1-2Tb drive.
