Powermac G5 1.8Ghz June 2004 won't boot anymore
Past week i've bought a second hand PM G5. At first it seems to be all ok, but right now its not working anymore.
I've managed to install the OSX on the first evening i've had the PM G5. After installing evrything seemed to be fine. But after 30 minutes surfing on the internet, it froze. I had to give it an hard reset by holding down the power button.
After turning it of, it won't boot anymore. after a few times trying with 10 secconds between it, i unpluged the powercabel for 2 minutes. Wile turning it on after 2 minutes, it was booting , but it stopped booting after 1,5 minute and froze.. after hard resetting it, i've managed to boot it right. The OS seemed to be ok again, but after 5 till 10 minutes it froze again.
Right now it won't boot anymore... it starts (without the front light, this light only blinks fast once i turn it on, but after that no more. Sometimes it won''t even flash.
I've been buzzy replacing some components to get to know if it was a hardware fail. I've first replaced the PSU with two other PSU's from the PM G5, but won't do a thing.
The i've replaced the memory with 4 kind of difrent pairs, but won't do a thing either. At last i replaced the Logic Board, this won't even do a thing about it.
Of course i replaced the PRAM battery first, but also this won't help me.
I've tested it in AHT, but evrything was working well, according to AHT. I've managed to get the system log, but nothing scarry though here also, only some 122 errors some times. (download the system log here: http://www.mijnbestand.nl/Bestand-F4DDN66WLRCI.log )
I've reset al things possible like PRAM reset, PMU reset. Nothing seem to be working.
What can i do next to get this thing work?? I'm getting nut's here..
Please help..
Thanks a Lot
