    Went on my iMac G5 17" this morning turned it off, no problems. Hour later i resumed what i was doing, turned it on and nothing. The iMac won't boot. All i get is a blank screen the fans go on overtime, sounds like a jumbo jet and the light appears continuously on the front panel.

    What do i do?

    Was this because of passing storm? That you shut it down.

    I would try unplugging all the cables that are connected to ur comp (and I mean EVERY cable: power, ethernet, etc.). Then wait for like 5 min or so, then replug everything, then try it. Hope this works :)

    I've tried everything and nothing seems to work. I've removed ram from inside pressed two buttons to reset but nothing seems to work. I tried removing all the cables, but it seems more and more likely that i'm going have to take to the 'experts'.

    fans revving up normally means a pretty intense hardware problem.. like the mobo/CPU or something like that (dont quote me tho).

    have u tried holding down the power button until it beeps??

    I tried but no beep. Just the light disappears and the fans still kick in.

    Try holding down the powerbutton "when you turn it on" until it beeps.

    This is my conundrum, i've had the iMac about 5 years. I've also been reading that the iMac G5 isn't very good generally. It's had many notorious problems.
