Neither do I.
but in this forum is such a huge knowledge maybe somebody have seen this:
Or can describe what is going on.
i experience a strange boot/start up behaviour of my good old G5 since moving to leopard and PT8. every morning when i "power up my controlroom" my mac wonīt start properly at the first time. the mac stays on the white apple screen.
Before this happens, you should hear a startup chime. That chime indicates that the G5 passed its POST, or Power-On Self Test. After that chime, you should see a white screen with an Apple logo. At this stage, the firmware is directing the computer to load the booter file. If this is successful, then you will see the spinning gear icon beneath the Apple logo. The spinning gear icon indicates that the kernel and subsequent files are being loaded.
i allways have to force shut down (with holding the power button). after powering up again everythings starts normal. strange?
Strange indeed. When you power up your control room, are there external peripherals attached to the G5 that turn on with a single (or master) switch? What would happen if you turned on only the G5 tomorrow morning? When you force shut down and then restart, do the cooling fans of the G5 ever ramp their speed up before the screen takes on a blue background?

When the system hangs at the point of the white screen with the Apple logo, I think of a hard drive problem. This could either be physical failure, or it could be file system corruption, as it would be unable to properly locate, let alone load, the booter file. If you can, startup off of the Leopard DVD you used with this system, and choose Disk Utility from the Utilities menu once the DVD loads. You will want to verify, and if necessary, repair the Macintosh HD.
maybe a HD failure or known os problem?
HD failure, maybe. Known OS problem? I doubt it. Apple's QA may be bad, but I don't think it has gotten that bad...yet.
system specs: g5 dual 2gig / 7mb ram / os 10.5.5 combo / PT8. everything installed from scratch with a new seagate barracuda system drive.
Ah, Seagate. Wise choice.
