We have what I call the "Volleyball" iMac, G3, out of applecare, which has been working fine except the internal HD died and had to be replaced a couple months ago. My wife just called me from her office, that when she went to turn it on, the photo of her desktop appeared, but boot didn't happen, then it blacked out. I had her hold in on/off button for a few minutes until light on screen turned off, then it booted okay. Later today I'm going to her office to run some diagnostics, maybe Disk Warrior. Any other suggestions as to what could cause this behavior and what steps to take (besides a thorough backup, which is on the agenda)? thanks, -don -donald henry hinkle --------------- Please remember to help feed the starving—click daily on http://www.thehungersite.com AND http://www.thechildhealthsite.com/ AND http://www.theanimalrescuesite.com
