Hi everyone, Bad news for me. I have a white iMac 24" and i was watching a movie the other day when i heard a really big "boom" sort of sound and the imac was dead. it sound as if something had a shortcut inside. Im familiar with pc but never opened a mac before. Can anyone give me some clues about what could happen and also maybe a link where i can find some technical stuff about what kind of power supply, logic board etc.. it uses and where to get spair part to repair it. Also "how to open it". Thank you.
