This evening while browsing Facebook on Chrome my iMac froze. No spinner and no mouse action.
Restart with the power button gave the start-up sound and you can hear the disk ratlle. That's it.
No sign of life on the screen. Pressing a key gives a sound but nothing happens.
It's an Intel iMac 17" dualcore 1.8ghz. Last month I replaced one of the 512mb cards for a 2gb.

No luck with command, option, p, r.
No luck with command, option, o, f.
Sound comes up but nothing on the screen.

Hope you have an up-to-date Time Machine backup.
Try shutting it off, unplug, press the power button (yes, I know it's unplugged, this drains all residual capacitor power), leave it off for about 10 min, plug it in again, then turn it on.

Everything is save in timemachine.
I bought a cable to use a second screen. Again, no luck. Maybe that has to be turned on in prefferences? For me, the extra monitor says; "'No Input Signal''.

Watched some YouTube videos about opening an iMac. That is not difficult but what to look for is the question. Screen? Video are?

Does it boot from the OS X installation DVD? If so, see if the hard drive is visible in Disk Utility.

it does boot. I can hear that. Screen does not turn on, I attached a 2nd screen but that one says "no input signal"
I'll call apple tomorrow, maybe they can see what's the problem. Graphic processor?

Could be that your screen backlight is dead, or the screen itself.

Had this exact same problem with my iMac about an year ago. Was covered under my AppleCare protection plan. They had to replace the mother board. Working fine since then.
Advice - use a surge protector or a UPS to connect your iMac to the mains.

Remove all accessories and connections.
remove power completely!!
Wait a few minutes.
Try booting using PRAM reset,
Try booting with startup extensions disabled.
Try booting ONLY with an external screen attached (if you can).
If you have another OSX machine of same OS, try booting into Target Disk Mode.

I cleaned the inside. Lots of dust. Now I don't even get the startup sound. I think it's officially dead now
inside my iMac

Look for the PRAM battery ... locate the same type of battery, replace without power cord connected, then reconnect Power Cord - you should here a "click" from the power supply once connected.
Power device using PRAM reset, then re-power on iMac. I hope this really works for you.

I noticed the battery. Forgot to measure if it was ok.
I replaced the ram with the original ram and my startup sound is back now and i can hear if i press a button on the keyboard. Already found out that graphics is integrated on the logic-board. Still nothing to see on the screen. Used boards go for £50. Tempting to try but a waste if I fail. Somehow I want to fix this myself. I did with my heating system, dishwasher and car.

Changed cell-battery but no luck.
Next step is to replace the main board.
Not really available in the Netherlands.
EBay is a big risk, I think.

20-24 21-27 but upgrade requirements means beef up power requirements soldering skill and know electronic principle
and engineering how power supply works. New iMac is different beast altogether slimmer no dvd, upgrade ?? with exempt 27" where memory upgrade available at price New Ivy Bridge Interface Better GPU Nvdvia Faster CPU QUAD core. (( Thunderbolt)) is a replacement for firewire a/b , replacements minidvi minidisplay universal port new technology If decide purchase max out, as this not user upgrade. Do you research as future model no longer for people be modify. alternative android smart pad ,ipad3 best luck

yep, that's the one. I'm not really interested in the latest iMac. I prefer the model before, I'm not ready to live without a dvd-drive.
My wife ordered new glasses so funds are low now.
I'll find a way, may take a while but I'm determined to get it running again
