Holy crap dude. Same EXACT thing happened to me. I take perfect care of my Gamecube and about a week after the warrenty expired it no longer read any games. About a month later I decided to call them and tell about this (I had already had my SP repaired). They extended the warrenty, picked up the GCN via Fed Ex, couldn't repair it and gave me a new GCN in 3 days. All this happened without spending a penny. But, yes, to get numbers, you can check on the back of your products to for the repair number.
