Hi folks, Over the past couple of weeks, my Mac Mini (G4, 1.5Ghz, 1 GB RAM), which is running Tiger, has started to crash frequently. I can't seem to pin point what is the cause of the issue, which normally allows me around 5-10 minutes of up time, before showing the greyed out 'hold the power button down' screen. The machine will run fine for hours however if left alone and not used. Which applications are open, or being used doesn't seem to matter for triggering a crash. After searching through old posts/FAQ pages, I've tried repairing and verifying permissions, and also verifying the disk too... nothing seem out of place. I've also run maintenance scripts (via Onyx). There doesn't appear to be any direct relation to the issue and any new software that I can think of either. Crash reports are mentioned on restart, though I've not been able to find them in ~/Library/Logs/CrashReporter. Can anyone please advice me how to start and track down a cause for crashes? Many thanks.
