Perhaps a dead PRAM battery? (Does the clock keep time each restart?) If you're getting absolutely nothing, the place to start it the Power button on the Mac. The translucent plastic is very brittle and sometime breaks so that the button quits working, it won't press the internal button behind the plastic. If your USB Keyboard has a Power button, there's a chance it would work? If the Power button is OK, then you'll want to think about the power supply. I'm not real familiar with the insides of iMacs even though I have two (not in use). If there is no power at all, you're looking at the power cable and the power supply. Perhaps there's a fuse that's blown? (BE CAREFUL!) If there is any power at all, or any keyboard command, you'll want to reset the PRAM/NVRAM by holding the Cmd-Opt-P-R keys for several chimes, and then immediately after a chime move the P & R fingers over to O & F so you're hold Cmd-Opt-O-F and at the open firmware prompt type: set-defaults<Return> reset-all<Return> where <Return> means hit the Return key. You should see a reply "ok" to the 1st command, and have a restart with chime to the 2nd command. Hopefully that restarts it? If not, you may have a bad HD. Try booting a CD hold the "C" key after a shutdown. If you can't get anything to boot from CD, you may be able to mount the HD onto another Mac by booting into Target Disk Mode by holding the "T" key at startup. If this works, you should have a Firewire symbol on the monitor. Then attach the iMac to any other Mac with a Firewire cable and the iMac will be exactly like an external HD mounted on the other Mac. You can run Disk Utility, or reinstall an OS X Combo Update, or whatever. Another thing to think about is firmware. Sometimes people upgrade to OS X without remembering to upgrade the firmware to the latest 4.1.7f4. If you've forgot to upgrade the firmware, you must boot OS 9 and run the updater from OS 9. Don't ever repair any OS X HD using OS 9 utilities. Hope this isn't too much info? Good luck!
