I'm fairly new to macs, and I've been trying to install OS X v 10.2 on an emac. the system profiler (?) told me it is a powerpc G3 with 256 RAM. Every time i try to install, i get to a point in the process and the installer quits, leaving me an error message. I understand this is probably to do with a dirty cd, but thats not the issue i'm most concerned with. when i try to boot as normal form the hard disk, the system just hangs on the grey screen at the start with the apple logo.I get that screen with static looking pattern over a horizontal band half way down. it also seems that the installer is leaving files on the hard disk each time i run it, as my available disk space is dropping. have i killed the imac? help!! i just want to be able to boot as normal!! my boss is going to be angry!!
