"You need to restart your computer"?!

Hi Everyone,

I'm on a iMac G5 Tiger 10.4.1
Everything's working fine.
When I go to shut down this message "You need to restart your computer" Hold down power button for several seconds or press restart" comes up in four languages.
I gather this may be something to do with "Kernel Panic"?
If I push the power button the computer shuts down. If I don't push the power button, after about a minute or so, the fans go full belt and I have to turn the power off to stop it.
On re-starting a panel comes up saying "The computer was re-started after Mac OSX quit unexpectedly"

Can anyone help with this?

Andrew

Sorry,
I think this is in the wrong section, but still, someone may be able to help.

Thanks,

Andrew
