Back when Halo 4 came out, I was very excited and (needing a new console) decided to purchase the Halo 4 bundle. My console worked great for about two months before something happened to it that made it not read game disks properly, prompting my to get it repaired (it is still under warranty). I just received it back in the mail today, and it doesn't work properly. It is freezing constantly (though it seems like it might actually launch games now). I am more than slightly frustrated that my console is having so many problems so quickly. Anyway, the console seems to freeze very quickly any time it starts to think (launching a game, transferring data, downloading an update), which makes it basically impossible to do anything with it. It never had this problem before I sent it in to be repaired (by Microsoft).
Anyway, any help on troubleshooting or anything would be very helpful, as I am honestly getting close to giving up on it at the moment. I don't want to, as I love playing and everything, but the problems I am experiencing are getting way out of hand.
