My XBOX 360 had the 3 red lights appear just after a year of having it - apparently this is a fault all XBOX 360's have, they die after a year. And my warranty had just expired - luckily my friend works at GAME so he sneakily let me pay for a 3 year warranty which I think was £30 and gave me a new one. I would advise to pay for the 3 year warranty when you get a replacement. And make sure you dont have it stood long ways up, and never have anything covering it, as it easily over heats. CALL OF DUTY 4 ROCKS!
