I've been having periodic crashes for quite some time now. The Mac will crash exactly 7 days from the time I boot it. Currently I'm on a cycle where it crashes every Saturday evening. FWIW, the weekly maintenance scripts don't run on Saturday (and every crash has been at a different time of day than the weekly scripts launch time).
Crashes occur in one of two flavors. Either the monitor is completely black, and the system is unresponsive to remote connection from my Windows PC (which normally can see the Mac file system), or I get an error message saying that the Mac crashed and must be rebooted.
Checking the Console log file, I see that a Software Update was apparently initiated just before the crash occurred. But if I do a manual update (click "Check Now"), it completes normally. (I've done this when there was an update to install, and when there was not.) Originally I had Software Update set for weekly updates. Now I've changed it to Daily updates, but it still only crashes on Saturdays. I see from the Console log that the software update check is initiated every day at the same time, but only on Saturdays does a crash occur.
I'm running a Mac Mini PPC, with OS 10.4.
