Ok, I bought my 360 two years ago and I am afraid im about to ge the rrod, I dont have areceipt and im not sure how to handle sending ti back when i eventually get the rings. how long does it take to get it back? how do you start the process?

Go online to xbox.com.

The serial number is all you need; they know how old the things are...

About a month ago my 360 got the rrod. I called MS the next day. I received a box about 3 days after that. I boxed the unit up and took it to the UPS store. I received a working 360 about a week after that. All together it was less than 2 weeks before I was back gaming. I was surprised that it didn't take longer.

BTW. there is a whole thread dedicated to this. here
