It turned out to be one of my harddisks, i removed one and it just booted. Oct 25, I noticed my Power Mac G5 dual core 2. Now it won't power up. No light, clicks or any other signs of life.

Power Mac G5 won't turn on

Tried all the tricks, battery, reset button, etc and nothing worked. I would be simply giving up on the beast and upgrading to a new box, rather than a costly repair, however get this, the same machine did the exact same thing about a year ago. I gave up on it then too after trying to similarly fix, but about a month later I was moving my computer station and decided to plug it in, I pushed power and presto, it started right up.

It has been running fine without any problem at all, for about a year, that is until this morning when I noticed it had again shut itself down and would not start up. I am hoping the information about it starting after a long rest will give someone a idea as to what may be causing this to happen again.

DeltaMac Tech Apr 5, Just so I understand - your PowerMac G5 will not turn on when you press the front panel power button. Is that correct? But, it will turn on when you press the power button on your Apple display Is that also correct?

Does that front panel light ever come on, or start flashing? If yes, does your PowerMac boot and run OK now, except for the power button?

If you CAN boot to your installer after getting power through the display power, then you should be able to install OS X. Last question - What did you mean by the 'board switch? That can't work - your G5 is too new for that.
