I've got a 20" iMac G5 2Ghz that is behaving oddly. When you turn it on, it starts up, chime and all, finds the system folder, and proceeds to the gray Apple screen where the start-up animation spins for a few seconds like normal, then the screen turns blue and the finder refuses to load. The cursor usually comes up and I can move it around with the mouse, until the start-up animation shows up again and start spinning, and spinning, and spinning...
If I leave it on long enough, sometimes the fan will kick on in high gear, but not always. I tried booting from a DVD, and I get the same behavior. Zapping the PRAM had no effect at all. I opened the case, blew out the dust bunnies and checked for bad capacitors. The capacitors all look healthy. I've had enough of these particular iMacs have caps go all bulgy, so I was pretty sure I'd find the problem there, and was surprised when I did not. I did not notice any odor coming from the power source, but I did not remove it to look for evidence of bad caps in the power source. I'm not getting the usual symptoms of a bad power source (won't turn on , turns itself off intermittently, fans blowing loudly ALL the time), I just can't finish the startup sequence.
