A dual 2Ghz Powermac G5 I bought in December 2003 failed to restart in February this year after I replaced the PRAM battery and it hasn't worked since. I've tried all the recommended resets but it won't start so I'm considering replacing either the logic board or the PSU. 'Trouble is I don't know which is faulty. Here are the symptoms:
1. Single click sound near the PSU when the power cable is plugged in.
2. When the power button is pressed:
- a. The power light comes on and stays lit as long as the power button remains pressed
- b. The 2 CPU fans are momentarily jolted, along with a single click sound so some power seems to be transmitted
3. Nothing else starts
4. Same single click sound as 1. when the power cable is unplugged.
The thing is so heavy I can't get it in for a repair as I don't drive so I have to determine categorically which part has failed - PSU or logic board. Any help appreciated.
