Successful start, Activity monitor shows TWO cpus and after a few minutes, system freezes. No mouse movement, no clock Successful start, Activity monitor indicates 1 cpu all apps work fine for a couple of hours (like the present moment ), subsequently followed by tremendous loud continuous high intensity fan activity and SPOD, after which I manually shut down with power button

Also, at times, the following error log:

I attempted to remove the rear fan assembly, but couldn't get past removing the metal cover with 2 G5 logos.
Any help is greatly appreciated
Cheers, Les





if I find a moment or two I will send you step by step photos on this @mail [??] to you ..... it is not hard but do a test first on some dead mac g5 before you try it out on yours ...

as for the symptoms try to let the g5 rest for some time like a vacation........ unplug it and for get it for 2months then start it up again.

I have the same problem with mine ...... the is not how to fix it but how to live with it !!! what happens is, the cpus are not reciving electricity so it could be some resistor from the power unit>on the logic board> in the cpu's > bla -bla .... SAY did you have any usb plug problems any time ????

get back to you soon
joho




well if it works let it be ,
but still pick up a second mac g5 and work then. two months the one, then two months the other, I work on mime 18 hours a day at 70% I had many different and strange things happen...

had one crap out died just like that.
black screen the light flashing thee times thing was dead as a doornail !!! put it on side for 7 months then one day just from curiosity plug to the wall pushed the start button-
worked just like a charm??????????????????

thats all

joho
