Hi, I just bought a PS4 and when we went to play a game it worked fine...then I went to put another game in there slot and it took long for the system to accept it. I had to give it a little nudge and when it finally went in the system couldn't read it. It would spit it out, I had to keep pushing the eject button. When I went to take the system to another room I heard something in there moving around. What to do?/??
