So about every fourth of fifth time I start the game, just when the information comes up telling me that the game is in Alpha etc. comes up, my whole computer freezes except mouse movement and this exact song starts playing: (it's the He man sings "what's going on"-song). I can't even get the task manager working. I can however press ctrl-alt-del and then shut down my computer with the mouse. I've done several virus checks, I have verified my files through steam, nothing suspect is going on. I use windows 7, firewall on etc. Any ideas? First post, sorry if it's in the wrong department. //torr
