My memory is a little fuzzy but: My first 360 lasted from January 2007 to November 2007 (died the day after I got Mass Effect 1, Assassins Creed 1, and Super Mario Galaxy--not on 360 but I got it on the same day as the others.). It died again in November 2008, immediately after I got Gears of War 2. I didn't get it repaired. Instead, I got a new 360 in January 2009 (and sold the old one after transferring my data). My new Jasper 360 died (no RRoD, just disc drive failure) in January 2010--Immediately after I got Mass Effect 2! So, I feel your pain.
It makes you hate Microsoft and if you have any other consoles, you'll hate playing them until your 360 returns. It'll pass. Just be strong.
