Q:
A: My first 360 was used and a little after a month, it got the RRoD. I had bought a warranty for it at Gamestop, so I took it back and got another one. That one froze frequently and made odd, grinding type noises, so I traded it in (they took it, because from what they saw, it worked) and took that credit to buy a new Arcade bundle last November. The new one has worked fine, every since. No problems, whatsoever. So, bottom line is, get a new one.
