For the last lot of weeks, whenever I've had a disc in the PS3 and switched it on, it doesn't come up with the game name so I have to eject it and put it back in for it to play properly. Sometimes it even freezes and gets quite glitchy. It's happened on quite a few games.
I've tried hoovering the disc slot but no luck. The PS3 attracts so much dust it's unreal.
