Steam stopped working

So it goes like this. I tried to help a frien add some GCF. Then Garrysmod stopped working. Then he deleted the local content for Garrysmod. Then reinstalled it. Then Steam whent all crammed together. All the text and buttons where in one spot. NOw he just restarted and steam can’t open up. Exept from the tray icon. He isn’t connectet as far as I see on the friends-list. If he tries to right click then choose one of the options, Steam just vanish.

What do you mean, “Steam went all crammed together”?

Did your friend try restarting his computer first?

Yes. Crammed together, all the text and buttons are ontop of eatch other

Reinstall Steam, it is quite simple
