Red circle of death xbox

As previous poster mentions if its under warranty send it back if not:

When the Xbox 360 overheats it causes the lead free solder to crack, the more that crack the worse the
machine will get. So eventually I suspect your machine will die completely and show either 3rrod or e74.

To remedy this you need to strip the console down and replace what's called the X-Clamps, at the same
time replace the heat-sink paste and then you need to re-heat the whole board. We use a special IR over
which re-bakes everything and re-seats the solder properly, a lot of people use a heat-gun but you have
to be very careful.

Call Microsoft, let them know you have the RROD (Red Rings of Death). They will have you ship it into them, they repair it, and send it back. All with the assumption that your xbox is not older than 3 years old.
