I have a 1.42Ghz eMac, with 256MB RAM. I am trying to re-install the OSX, which may have been corrupted (or the HD is faulty). I inserted a Leopard DVD, and it loaded the installation, but as it was loading I realised that 256 MB is not enough for Leopard, so I powered the eMac off. I then inserted another 128MB module (pulled from another Mac, both are PC2700). I then inserted a Tiger installation CD (not DVD), but it just keeps automatically ejecting it without loading anything. It now doesn't even load the Leopard DVD - I've even tried removing the 128MB module, but it just keeps doing that. Any ideas?
