    All of a sudden the iMac monitor went black and the computer was still on. I restarted it and nothing doing. The white light is on but the monitor wont turn on? Oh man, what happened here?

    If you shine a bright light on the screen, can you see anything? It could be a backlight issue.

    I unplugged every cord from the iMac and then plugged them back in. It is a heat/memory issue where if you leave your computer on for too long, it will black out.

    I've fixed it twice now. But when it comes back on it only lasts for about 3 minutes. I can login and get to my desktop, but then it goes black and I am forced to force shut down and unplug everything.

    Any warranty left? If so, I'd call/make an appointment with Apple immediately.

    Read carefully. It is not fixed.

    I do have a certified Apple repair shop about 40 minutes away. Is there anything I can do? Like a reset inside the iMac or something?

    Oh sorry, I just saw the problem solved and assumed it was fixed. I didn't read down any more. I think your best bet would be to take it to a repair shop and see what they can do for you. You could reset the PRAM but I don't know how much good that would do. You said in an earlier post that it was a heat/memory issue. At the bottom of this article it details what the PRAM contains and the RAM disk is one of them so I would try it.

    Yeah I did say it was a heat issue. I think I was wrong. I think I'll just take it in to the repair shop sometime soon. Thanks for the help though.

    I tried a 'key-holding' method earlier today and the screen still doesn't turn on. :apple: + Option + P + R.

    Yeah, instead of messing with it that is what I would do. Sorry I couldn't offer more help
