Hi, This is my first time posting, but I read here a lot. I just got a new 2.4 Santa Rosa MBP, so I was doing a clean reinstall of Tiger onto my old iBook because it will be going to my parents. It was on disk one and installing when all of the sudden it shut off. Now, it won't even turn on. The OS DVD is also now stuck in my optical drive. Does anyone know what could possibly be wrong with it? It's still under AppleCare, and I just want an idea before I take it in. It was working without any problems. Thanks!
