    So I recently started having a very strange problem with my G4 Cube 450 mHz. It just randomly decides to turn itself off or to go to sleep. I really have no idea what could be causing this. I'm be using my computer to surf the web/chat/or play computer games and then all the sudden the screen goes black, the little power light fades out and it shuts down. Or sometimes the screen goes black and I can hit a keyboard button and it'll come back on. But still I don't understand why it's doing this. Any ideas? There's nothing on top of my cube or anything near the power button and I have the energy saver settings set to never sleep. So any help you can provide I'd really appreciate.

    This can be caused by many things. www.cubeowner.com has a plethora of resources specifically for cubes.

    Some of the G4 Cubes had a defective thermal sensor in the touch sensitive power button that triggered random power-ups. This may be the problem with your computer.
