Have you tried a clean install?

Well, all things being equal you shouldn't be having a problem. I have an eMac and made the jump from 10.3.9 to 10.4 without a hiccup.

If your present 10.3.9 is operating normally and there are no special hacks involved you should sail right into at least 10.4, provided you have a legit install disk - in other words, a retail version. If you use an iMac 10.4 system restore disk (one that was bundled with an iMac), well, it will work great on an iMac but not necessarily on an eMac. I don't know where you got 10.5, which is only in developer preview form right now, but there may be issues there as well. 10.5 is definitely not public software at this moment.

So, to further diagnose this, was exactly is the source of your 10.4 disk? Where did it come from? And how did you come into possession of 10.5? Are you a developer?
