Thanks, Geekcop and Weedahoe. I thought I had subscribed to email notification, but must not have done so correctly. Good thing I checked manually today!

I'll try memmaid (I've often used SKTools and will rerun its program again, too). It sounds, however, like these programs will remove (legitimate) garbage files, accumulated over time.

I suspect that my problem is with the ppc's memory having defective sectors, which when accessed give rise to problems which mean I need to do a hard reboot.

Any suggestions regarding possible defective sectors of memory?
