Closed Stam closes (Crash?)

So I bought the game, steam was working perfect.. I was waiting for the steam key and when it came out I activated it. Then I was waiting for the Starbound (Installation). When it showed up I clicked ''Play game'' and then ''Install'' after this steam minimized to the hidden bar. I wanted to click on the Steam icon and it just dissapeared so I wanted to open Steam again it closed on startup. I tried to delete all steam files expect steam.exe and steamapps and install it again but it was the same. I can't put any screens, because I have nothing to show you guys, because I just didn't get any error. If who knows the solution or other helpful stuff please write here. Thanks, Michael
