Hi,
My Mac = Power Macintosh G5 Dual Core (2.3) Specs (Late 2005, M9591LL/A, PowerMac11,2, A1177, 2023) @ EveryMac.com
Problem: Fails to boot - doesn't even give a startup chime. I can hear the HDD starting up, and the fans start ok and then go super speed after a minute... power light is obv on... but nothing else. No chimes, no errors, no video, no nothing.
I took it to a busy Mac shop who said to replace the memory. I replaced it with new Kingston memory and the problem still exists. I have tried the various methods of troubleshooting to no avail.
I have spent the last few weeks turning the thing on and off whilst busy working at my desk, in the hope it might start again so I could access some files. I positioned the RAM in the wrong slots and got the approriate chimes. I then positioned the RAM correctly and hey presto it booted up just fine! I copied my files and was dead chuffed. However, next time I shut it down it failed to boot again Repeating the above scenario no longer revives the beast.
It would be great if I could rule out the Logic Board based on the presumption that if the board had failed, the previous one-off successful boot wouldn't have happened. The capacitors all look great.
Run out of ideas now - the Mac shop seem completely uninterested and have suggested the logic board without actually testing it.
