I have an iMac G5 Rev. B (the last one before the iSight came built-in) that appears to be dead or dying, and I'm trying to figure out what to do with it. I'm hoping it is still worth something to someone, and I may be able to get a little cash to put toward a new machine. The machine was always reliable and covered under Applecare, but at four years old the coverage has expired. After applying the 10.5.5 software update, the machine never rebooted properly. The machine boots, plays the startup chime, displays the proper grey screen with apple logo, then goes to a solid light blue screen and stays like that for as long as you leave the machine on. Two times the fans turned on to hyperspeed, but it hasn't happened in over a week. I've checked the machine every day for signs of life. I was able to use firewire target disk mode to recover all my data from the hard disk, then I did an erase and clean install of 10.4 hoping it would have ended up being a software issue. With a fresh copy of the OS installed, the machine still behaves the same way. The machine's specs: 17" Display, 2.0GHz G5, 2GB RAM, 300GB HD, Airport Extreme + Bluetooth, DL SD.
