Hi guys,
When i start Call of duty 4 on my ps3 it works fine i can play single player with no problems but when i press multiplayer my ps3 screen just turns black completely and i have to restart my ps3 to turn it on again.

I can play online on any other game like Black Ops, Mw2 or anything else even online so i dont know what the problem is and there is not even 1 scratch on the cd pls help...

Thanks guys
