Awesome guide. Thank you so much. I did it, but now I just wonder what that white stuff was when I removed the motherboard. I think it's that thermal stuff people have been talking about and I suppose I have to replace that. I also hope that it's the fan that is what's causing my PS3 to say that it's overheating and shut off. I'm so glad you guys posted this. Great job. I rather do it myself than pay Sony an arm and a leg. Cheers!
