First, wasn't sure where to place this.
Second, this is something different. Usually someone has a problem and scours the boards and internet to find a fix. Well I'm gonna tell you what went wrong and how I fixed it in case this troubles you too.

My boss had bought me a 24" iMac 2.16 ghz dual core with 2 gb of ram. I loved it. within a month however I'd come back in the next day and find my computer with a blue screen, apparently it didn't like shutting down. So, after dealing with this problem I finally found a fix.

Shut it down.
Unplug from computer.
wait 10 sec.
When you plug it in make sure you hold down the power button.

Great, it comes on and shuts down. However the fans come on full force when I power it up.

It took a while to find the fix on this, which is why I'm posting this...

After you have fixed the shutdown problem, shut it down again.
Unplug.
Wait another 10 sec.
DO NOT HOLD POWER, but plug the power into the computer.

It should work fine.

And now you know, and knowing is half the battle.
