Try an Open Firmware reset of the video RAM. Press the power button. As soon as the iMac chimes/bongs, press and hold down the Option, Command, O and F keys. When the light grey Open Firmware comes up (it will take a while), take your fingers off the four keys. At the prompt, type this series of three lines, hitting the Enter/Return key at the end of each line: set-defaults reset-nvram reset-all As soon as you hit Enter/Return after the last line, the iMac will chime/bong and restart. If corrupted nvram was the problem, or if parameter memory was confused, this should get your iMac to boot to the desktop. This has worked for me countless times in getting iMacs, iBooks and other Macs with video-related startup issues/symptoms to boot. Good luck!
