Anne,
I use this this method every once in a while, and it usually works to
repair my hard drive.

I have been out of the country and away from my main iMac for about seven
weeks. During this time the machine was turned off (Shut Down) and unplugged.
No external devices were connected to the iMac.
Now it won't start up. Plugged in and turned on via button on back: first get "happy"
sound and the gray screen with the Apple logo but then just the swirling whatever. Then some while
lettering on black (terminal?) but it isn't up long enough for me to read. Whole screen goes black.
Then gray screen with message that "the computer has a problem with restart. Press any key or
wait a few seconds."
I pressed a key and got the gray screen with the apple logo back but no further until I
got the circle with a line through it indicating "no go."
Any suggestions?

Try starting up in “safe mode”.

The following is from Mac Help:
safe mode
Safe mode may help you resolve or isolate
problems that you’re having with your Mac.
When you start up in safe mode, your Mac
prevents some software, such as startup items,
from loading, and it performs a check of your
startup disk. Your Mac may take longer to start
up because of the check.
1) Choose Apple menu > Shut Down.
2) After your Mac shuts down, wait 10 seconds,
then press the power button.
3) Immediately after you hear the startup tone,
hold down the Shift key. You should press the
Shift key as soon as possible after you hear the
startup tone, but not before.
4) Release the Shift key when you see the gray
Apple logo and progress indicator.
To leave safe mode, restart your Mac again, but
don’t hold down any keys during startup. Once
restarted, read more in Mac Help; a good place
to start.
