    My 2 year-old iMac G5 shut down suddenly during use this morning, and without any apparent warning. It was as if there had been a power failure. Until now it has been entirely trouble-free. Later today, while I was logged out and the machine was in sleep mode, it shut down again. Any ideas, please, as to what may be wrong?

    Many thanks to both of you. I have a 20" iMac and I now know where to start looking. Thanks again.
