Luckily my friend came over and we played a bit o' Halo 3, setting up gametypes for the tournement. But, this isn't the most important thing.
I, because I'm an idiot, started taking apart my 360, after looking up the problem with it, hoping to be able to fix it myself. BUT if I can't find it, then I screwed it all up, beacuse I broke the seal inside the Xbox so I can't get it repaired.
I'm crossing my fingers here.
