I am using a G4 1.25 dual. A week ago I had problems booting up. I kept getting the "finder not responding" error. I relaunched, ran disk utitlity, disk warrior, started from another drive and ran everything - nothing worked. Finally I wiped the drive and reinstalled everything. Worked fine for a week. This morning the same thing happened. I am at a loss. What do I try now? Thanks for any help.
