I've worked on a couple of eMacs in local schools with similar problems. I've run Apple Hardware Tests, Apple Service Diagnostic tests, reinstalled OS X, cleaned out all the dust bunnies, swapped RAM sticks, run Memtest overnight, run DiskWarrior, yada yada yada. Nothing fixes the problem, but nothing is found to be wrong, except the crash log points to memory problems. Found a handful of bad capacitors on one eMac's logic board (1.25 GHz). It was really acting up, doing all sorts of strange, non-repeated things. Replaced all the caps on the logic board, and the software problem went away. The bad cap problem tends to affect 1.25 GHz eMacs the most, which coincides with bad capacitor problems reported by other electronics manufacturers in the 2004-2005 time frame. You don't say, but my assumption is that you've got a 1.25 GHz eMac. I've not seen bad cap problems with 700 MHz-1 GHz USB 1.1 eMacs, but I have seen the problem in USB 2.0 1 GHz and 1.25 GHz eMacs. I've only dealt with a handful of 1.42 GHz eMacs, and they didn't have any capacitor problems -- at the time. Trouble is, caps can be bad and not show any visible sign of failure, such as leaking, bulging tops, tilted to one side from bottom leaks, etc. Capacitors on eMac logic boards are relatively easy to replace and there are only a dozen or so to replace. Most of the work is in disassembling the beast enough to extract the logic board. So, if all else fails, try the capacitor replacement solution.
