I just got an xbox 360 from a friend. They have never played it and they bought it pre-owned. I just bought controllers and lots of games for it, and I went to go play it. Every time I play it is freezes up within the first 5 minutes. I don’t know a lot about xbox’s, but i’ve read online and I don’t have the 3 red line thing. it’s just green. What do i do?
