I recently bought a used ps3 from a friend and have come across a problem. On Red Dead redemption there wil be random blue or brown boxes or walls that pop out of nowhere and the mountains in the background will sometimes be made up of purple and green triangles. If you look one way there there and you tirn around they are gone. Also blue dots will appear on character and objects. Then in Modern Warfare 2 a simmaler effect is occurring but instead of triangles it's glowing patches of green and purple with little black boxes in the sky. Also whenever I attempt story mode or a single player spec ops it will go black and the only way to fix it is to unplug and restate the system. I am hoping someone can provide some insight to my problem. I mostly need to knownif it's disable or not. Any help is Greatly apritiated.
