    I turned the iMac on a few minutes ago and it came up with the normal white bootscreen but instead of the Apple and the loading circle it came up with just a flashing white and grey image of the world, I pressed the button on the back (not holding it down) and it turned off and when I turned it on again it worked fine and its fine now, but I just want to know what that was or what it indicates, is there a problem with the iMac?

    Thanks in advance!

    That's the indication that it's looking for a NetBoot server to boot from. This can happen if you hold down the "N" key during startup or if someone selects "Network Startup" in the Startup Disk system preference.
