[G4] What Have I Done To Deserve This

[Umar Stone]

Back in-front over the computer now, No It Is Not Fixed;
Well I must say I'm stuck with this one, don't worry about the cable  
select  Master/Slave relationship that is not the issue. That is fine.
I tried the RAM memory cards they didn't seem to be dysfunctional,  
taking them out  one by one.The problem did not cease.
Also using Disk Warrior located a few issues the printer's print  
option is unrepairable.

So while I get a Mac-Vac for the dust, what about backing up and  
totally reformatting my Mac, But I might just buy another  
Tower     .????????.

thanks everyone for your advice
