My dual 2 GHz G5 has developed problems and is currently hors de combat. A problem which started about a week ago and was, at that time, intermittent, has now become constant. The machine starts normally and will function for a brief period of time before freezing, at which time the drive is screaming and the machine displays a greyed-out exhortation to re-start. Etc.

Before the problem became acute I was able to run TechTool Pro, Disk Warrior and Disk Utility. No drive problems were noted and a few files were repaired. I also replaced the directory. As I am more than stuffed without CS3 or a machine that will drive a 30" monitor I would welcome any suggestions.

Both drives are backed up and the main drive is cloned with SuperDuper so I would lose only some recent installations if a new drive is indicated. I can't keep the machine running long enough to see if a reinstall from SuperDuper would be of any help.

I would welcome suggestions or observations regarding probable/ possible cause of the malfunction.

Do you have an external drive that you can start up from ?

It would need the same flavour of OSX ... ie to say Leopard or Tiger ,
that you are running on the G5   , and the version on the external drive
should NOT be later than what you are using .

IF you can start up and run OK from that external drive ( Firewire or eSata )
action a  combo update to the OSX you have on your G5 .

Assuming that clears the problem , follow it with Permissions repair .

I had a great day today using that technique
clearing the BLUE Startup SCREEN that hit me this morning at start up .

Have fun
