Xbox 360 E74 Error

[B16 RTT]

When booting up the 360, the bottom right quadrant flashes red and an E74 error message comes up.

Have been on the MS support webiste, but their solutions haven't solved the problem. Does anyone have any advice on how to fix this, or does it need to go back to MS?

Thanks guys,

Ricky

In short, it's buggered.

Has it not been booting up on the first attempt for a while?

Microsoft had no problem replacing mines when it started giving me that error, best bet it to give them a phone as the web help they offer it utter jobby.
