I got an odd one here. A friend brought over a 2008 iMac8,1 24" running Leopard10.5.8. She told me it had been in storage for a few years and it would give a kernel panic if she did anything. So I booted it up and everything looked normal to me until I tried to do a software update, the the top of the screen turned yellow and black kinda like the yellow cab logo. Real strange, so I rebooted and everything looked ok again. I ran repair permissions and checked the disk and found no problems. I tried software update again and it work but found no new software. Now since everything looked OK, I tried updating to Snow Leopard. That worked OK as well. Now to try the Mavericks update as thats what she wanted on the iMac. That also installed with no problems. I again ran repair permissions and checked the disk no problems. Next I tried doing the Mavericks updates to the OS and applications. Now the problems start. After the update I got to the login screen but when I went to type in the password the whole screen image shifted to the right. Real odd. I rebooted and now the keyboard and mouse couldn't select anything and I couldn't type in the password either. Again I booted into single user and ran fsck -fy and it said everything was OK. Then I reset PRAM. Now to boot and now it hangs with the spinning wheel of death. Then it freezes. I tried a safe boot and that worked although it took a long time to boot. I even tried booting from the external firewire drive I used to install Mavericks and no joy. Any ideas as now it won't boot at all it just sits on the gray screen with spinning wheel.

You really do have an odd one. The only thing that occurs to me was that the early 24" iMacs had an issue with the screen. I think they did a recall or were doing repairs.
