I came here because I've been lurking for years, and know how expert you guys are at PowerPCs. I have a 2002 Quicksilver, 933 processor, all stock except for RAM I upgraded when I got it from DV Warehouse several years ago. I keep it turned off unless I'm using it, but lately it has taken to starting by itself randomly. This morning it was asleep, then woke up and went right back to sleep over and over. I barely had time to get to the shutdown command, but it wouldn't shut down, so I unplugged it. I tried resetting PRAM previously, I've never had it set to restart after power outages, not connected to a network. No new hardware in years, no new software except TenFourFox two years ago. It's had the same modem as long as I've had it, nothing new connected to it for several years. It's working now so far after a safe boot. What possessed my workhorse?
