Thread: Yet another dying PowerMac G5- kernel panics galore

Started 2 months, 4 weeks ago by eek
First post- whoo. Well, I have a Dual 2.0Ghz PM G5, late 2005 version? I think it is. A few weeks ago whilst surfing the net, it froze, had a kernel panic, I reset the computer and all was good again (so it seemed). Last week, I couldn't boot my computer at all. It got to the grey apple logo screen, with the circle progress ring, and freezes there. It currently has a new 1TB WD ...

Usually kernel panics are caused by either bad ram or a bad video card (or bad CPU). Are you 100% sure all of your ram & video card are good? - Nick

I am sure the RAM and video card are good, not sure about the CPU though. I don't have the original G5 installation discs with me, so I can't run a hardware test. I have 6 sticks of RAM, and have tried a combination of all 3 pairs, on different slots, yeilding the same results. I have an ATi Radeon 256mb 9800 and nVidia 64mb GeForce 5200 video card I've tried and both have the same results...

Well it is NOT a late 2005 Dual Core model as they do not run AGP video cards but PCIE cards. Also the problem may well be a dying hard disk drive. When you get your install disc, boot from that and run Repair Disk and see what is reported. Also up for consideration is the logic board as earlier G5s had this problem. Without install and/or system discs you are diagnosing blindfolded.

Umm, it's the one with the 8 ram slots and AGP slot. 2004 then? As for the HD, there is a 3-day old WD drive in there with a fresh install of leopard. It's probably seen less than 3 hrs of power. I managed to boot up the computer and install leopard with a retail version of leopard, get to about 99% of the install and have the computer crash. Booted it up again, and ran through the ...

Many many times these kernel panics are the result of newly installed hardware. Since you are sure the ram & video card are good...and we will assume for the moment that the CPU is fine (since folks usually don't swap these in G5's)...then the only thing left is that new hard drive. I would say remove that new hard drive...put an old hard drive back in...and see if you still get the ...

It's probably not important at this point which 2.0 ghz G5 you have...but there were three different versions of the PowerMac G5 with a dual processor 2.0ghz CPU's. Of these three...two had 8 ram slots. Then ...

The HD is a Western Digital Green Power drive. I had the stock 160gig and that drive in my system for about 6 months before this with no problems. The newly purcahsed drive, with a fresh leopard install is also a Western Ditigal Green Power 1TB. My intention was to run two of these WD 1TB discs as raid 0, since they're identical. The weird things is, I didn't change any hardware ...

Good luck! - Nick

Pop in disc one when you are home, reboot and hold down the option key. The drive and Apple Hardware Test will come up as options to boot from.

eek replied 2 months, 3 weeks ago
You know what's really freaky? I formatted the HD when I first put it in the computer with disk utility and installed leopard fresh. I checked again last night and htere were millions of disk errors when I clicked on verify disk. I just decided to erase and install leopard again. All seems to be going well...until I got a kernel panic updating 10.5.x...whatever the latest software ...

The lack of ability for the hardware test and mouse that doesn't light up is a bit concerning. Logic board failure? I could have 6 bad RAM chips also :s

Back it up about 18 posts in this thread...bad ram was one of the first things I suggested. Basically this system needs to be stripped down to the bare essentials...and only 100% "good" parts put back in. Then test stability. If stability is good...then add one & only one component back at a time. - Nick

Well remove all the Kingston and other random brand and just retain the original memory in matched pairs of course and see how you go. If things look good just add a pair at a time.
