L4D2 not starting all of a sudden!?

[GreedyLoU]

When I double click the game in steam the screen goes black like its starting then it goes right to desktop. No error message or any error beep. Tried verifing cache files and reinstalled the game. Any suggestions?

Maybe this is a resolution problem.
Right Click on L4D2 --> Properties --> General Tab --> Set Launch Option --> Type this code:
-windowed -noborder

Just a trying tip. So don't be angry and flame on me XD
