Hello Everyone. I just got a PS3 today and while playing Demons souls the system froze and the screen had "snow" on it, flickering between a couple different patterns. So I restarted and tried Dark souls, after a little bit it did the same thing. This is a used PS3 from Gamestop and chances are I'm going to be returning it tomorrow, but I would like to know what could be causing this. Thank you for your help
