I've bought a brand new xbox 360 s with 250gbs a week ago, and since then it has already frozen 3 times. The first one, I must have been playing for like 3h or so and then I put play on a demo an it just froze, I couldn't get back to the dashboard, só I had to turn off and on the xbox. The second time that happen, the game froze but still manage to get to the dashboard. So today it froze the 3rd time. I had my xbox turn on for about 6h, and I was just playing demos that I've downloaded from xbox live, and in the midle of the game it froze, I try do get back to the dashboard but It didn't work, I had to turn it off and on. So I just wanted to know, if this is regular to happen or if I should go back to the store?
