    I just bought my new imac on friday. Worked great for a day and then I had a problem. The fan came on really loud for about a good 10 secs and the screen turned off. I hit the power button and the screen came back on quickly like it had went to sleep. However, the fan came right back on very loud and the screen went black. I did this a couple times until I just let it shut down for an hour because I thought it overheated.
    The next time I turned it on it worked fine for about 3 hours and suddenly the fan came on super loud. This time the screen didn't shut off and I was able to continue but it was abnormally loud.
    This morning I turned it on again and within a minute the fan came on AGAIN. I have to mention that I'm not using any intensive application or anything. The last time I think I only had safari up. Also, this is my first mac and it's not looking promising...

    I'd definitely contact Apple if this is a new Mac.

    Sounds like you may have got unlucky and could be something faulty with the hardware.

    Either way, you have free support with a new Mac, might as well take advantage of it!

    I called the support line yesterday and the best they could do is have me unplug it for 15 seconds and restart. I think I saw better troubleshooting in the user guide...
    Well I have a genius bar appt for tomorrow so let's see what happens.
