I've got an oddball for all you mac gurus out there. This problem has been plaguing me for a while now.
I have a Begie MT (gossamer) with 256mb ram , the factory compliment of peripherals and PCI cards - then added a Western Digital 60gig drive and a newer technology g4 500 zif.
So the problem is this - when I have the machine performing a task that makes it think pretty hard, the monitor goes blank - like it went to sleep
but pressing keys and jiggling the mouse does nothing.
my original thought was - damn aftermarket zif!. so i pulled it and put in the apple 266 zif only to find it made NO difference. it was still blanking. Hmm, well, how about - bad logic board. not too big of a deal and since I have a gossamer based power pc macine i built this past summer sitting at a friends house, i started moving the WD60 drive, the g4 500 ZIF, and the 256mb memory out of the apple into the built machine that WORKS.
well, the problem followed me to the built machine. so i pulled the 256 mb memory. no change. NOW the only piece of hardware that was present in either machine when it "blanks" is that WD60 drive.
This seems odd, but not impossible, i guess ... /var/log/system.log yields no clues. I cannot boot to single user mode to make changes to the file system... I wonder if its that Newer Tech ZIF...
Anyway- I am stumped and if anyone has seen this type of behavior before or has an idea on which way to procede, please let me know. Thanks.
