Recently my G5 2x2.3mhz has begun to randomly switch off. It just switches off - click - and goes completely dead. When I restart it seems perfectly fine, and then - click - it switches off again. It has plenty of space in a cool room. I checked the temperatures of the CPUs and found they are running at about 70degrees Celcius. Is this okay? Any ideas why it's dying?

My iMac G5 sits at that temperature when it's working hard, but it's still stable-as-a-mule. What exactly are you doing when it crashes? What do you have in terms of third party hardware and software installed/active? Does Console (Utilities folder) tell you anything under system.log? :)
