I have a mid-2007 24" 2.4 Ghz Aluminum iMac with a probable dead logic board. One day I came home and it had a kernel panic screen up, telling me to reboot. It never started up completely, as it went into an endless reboot cycle. I tried re-setting the PRAM and unplugging all the plugs and resetting the system that way. That did not work, and now the screen does not even come up when I try to turn on the cpu. All I get is the fan spinning. Target mode does not work, and I cannot boot from the startup disk. I took it to the nearby Apple Store, and he was really no help-just another opinion that the logic board was dead. He quoted $750 to replace the board. I pulled the hard drive and have gotten my data off, but I am not sure what to do next. My options: 1) Replace it and hope that will fix the problem -I don't think I want to go this route 2) Try and sell what is left of the computer for scrap -I am not sure where to try and sell it besides eBay or Craigslist, and I am not sure what a fair price would be. 3) Buy a mac mini and try and use the iMac as an external monitor. - I know this is difficult to do, but it would save the cost of a new LCD with the same picture quality as the iMac screen. Any advice is appreciated, thanks in advance!
