iMac restars its self

[Mikey-]

When I leave my iMac say for about an hour the screen will go black and about 5 minuets later will turn back on and go to the login page. Anyone know how to stop this?

Mine does the same exact thing. Apple couldn't find any issues with it Stupid.

Go to System Preferences, Energy Saver, and set "Put the computer to sleep when it is inactive for:" to "Never"

it will always be on and ready to go that way.

and if you dont want to enter a password at all to get back onto your computer go back to System Preferences, Security, and uncheck "Require password to wake this computer from sleep or screen saver"
