My imac will not boot up!

[fixerman]

My iMac boots to the point where it has the apple logo on screen and the spinning gear. The gear stops spinning and it just stays like that forever. I have tried switching on and off a few times but it just stalls each time.

Please help!

There should be no reason to reinstall the OS. At worst, an Archive & Install may help.

What version of OS X are you running on your iMac? Has any software changes been made recently (i.e. Software Update or a newly installed program)?

Thanks folks! Disc utility did the job. All back to normal again. Panic over.
