g5 loses one core
I have had a whale of a time trying to work out what was up with my dual core 1.8 g5.
Have done just about everything imaginable from AHD, memtest, ASD 2.5.8. Disk utility,Diskwarrior. Reseated everything, changed bios battery, pram etc. etc.
The symptoms were and still are either, but not always
-hang soon after starting
-Kernel panic of a few varieties
-not boot into any boot volume (circle with a line through it) (ps. is there a name for that symbol so that it would be easier to search for)
All of these also led to max fans and a hard shut down.
I have done a clean install, no joy
removed the hard drive and used it to boot a macbookpro with no problem
The only test that showed any semblance of a negative result was the thermal calibration test on the ASD disc which failed both cpus. No other hardware test failed them.
And tonight may g5 seems to have taken some sort of self-healing action and shut down one of the processors. I now have a single core 1.8 g5! and so far it seems to work okay.
All which leads to my questions. Now that I am down to one cpu will that remain like that? Are the cpus replaceable? if so for how much? and how difficult? This last one will also answer is it possible to reseat the cpus?
Thanks in advance
