Random shutdown problem on G5 dual 2.3 GHz w/OS 10.4.7
I’m using a dual 2.3 GHz G5, and it’s been working flawlessly since I bought it about a year ago. Until yesterday, I was running OS 10.4.5. Yesterday I upgraded to 10.4.7, and as soon as I booted up after the install, I started having a maddening problem with my computer randomly shutting down. (Not sleeping, but a complete power down.)
At first, the shutdown would happen immediately after powering up; my computer wouldn’t even make it to the blue progress bar. I zapped the PRAM and tried something I found online about unplugging the computer for 15 seconds, then plugging it back in. It now boots up, and I can log in, but the computer still shuts down randomly.
There seems to be no pattern to the shutdowns. I tried taxing the processor by opening and resampling huge Photoshop files while lots of other apps were open, and things were fine. Then it would conk out while I was composing an email.
I’ve heard of this random shutdown problem affecting Macbooks, but I have yet to find anything about G5 towers and OS 10.4.7. Does anyone have any info/advice?
Many thanks.
