I've got a G3/266 Tower (400MHz processor, 512 MB, 6GB+2GB). It worked pretty much perfectly in OS X up until i moved to college. Now I see the apple and the spinning thing, but then the screen flashes once and doesn't start up. I fiddled for a while and now it doesn't start up at all. There's not startup tone and but I can hear the hard drive spinning up. I had it overclocked to 450 but brought it down to 400 and that's when nothing worked. I can unhook both hard drives and start up from an OS 9 CD but I can't start up from any OS X cd or anything. I tried the reset button on the motherboard and zapping the PRAM but nothing helped. Any ideas?
