hi folks using: iMac G4 800Hz, OS 9.2.2, 384 Mb RAM, 40 Gb H/D (and a few years old) prob: recently, a few minutes after booting up I hear a humming whirring sound that starts fairly softly but builds up over the next half hour to quite an irritating and distracting racket; I presume this is the hard drive or a fan? Another otherwise identical friend's iMac is as quiet as a (silent) mouse. Is this something I should be concerned about? And, if so, what can I do to repair or ameliorate it? Any thoughts? thanks in anticipation michaelP -------------- next part -------------- An HTML attachment was scrubbed...
