Hello,
I have a mac mini (power pc) and lately as I have been working on it it has twice forced me to shut down in the middle of what I was doing. I'll be working along and the whole screen fades black with the desktop darkened in the background and there is a message in the middle that says I have to hold down the power button and restart my computer. Does anyone know what would cause this?

There can be a variety of causes for your 'kernel panic', which is what that 'You need to restart your computer' message is called.
Here's a link to some info to help you find out the cause.

Some questions to start you off -
Have you installed or updated any of your major software recently?
Have you upgraded your memory recently?
Are you using an external USB hub, and what devices do you have attached to that (anything new there?)?
You should try the Apple Hardware test, which came with your mini
You will find either a separate disk, or the Restore disk will have Apple Hardware test listed on the label, with simple instructions for booting to that test.
Run the extended test, and get back to me with what you find out....

no, I'm not using an external hub.
