I have a powermac with a 1.8 GHz processor. Recently, it shuts itself down without any interference from me. The notification says that it has something to do with thermal runaway. When it reaches to 65 degrees C, it shuts down. Should I change my CPU? Or is there anyway I can remedy this without having to purchase another one?

Hello there! The first thing you need to do when this thing happens is to check the fans and the exhaust for dust build up. Always keep the inside of your powermac dust free. Also, check the thermal paste or compound in the cpu if it needs replacement. If these do not resolve the issue, you should bring your powermac to your local apple store so they can run a diagnostic test in it. Usually, the processor is broken and needs to be replaced. I hope you saved up money for that because that is quite expensive.
Good luck to you!
