When I came in this morning it was acting v-e-r-y slow and Open Office would not even force quit. I poer cycled and started out fresh without much open. All was fine when I left for lunch, but when I came back it was dead. The screen was black but when I tried tow ake it nothing happened, and it sounded like the hard drive was trying to access repeatedly every few seconds. Power cycling did not help, and now it won't even chime or boot at all, just the hard drive access repeatedly. This is an original Aluminum iMac 24", so it is not quite 3 years old. Yes I have Applecare but it is going to be a pain toting it into the Apple store (we can have Macs at work but they are self supported).
