G4 MDD 1.25 dual. 1 gig RAM OS 10.4.4 I recently had a rash of Kernel panics, applications quitting for no reason, and refusing to wake from sleep. I ran TechTool and Disk Warrior and Disk Utility, nothing bad reported. Ran OnyX. Then I installed a new HD and put a fresh OS on, updated, fresh install of my applications etc. Still had kernel panics, applications quitting etc. Zapped the PRAM, no change. Booted from a different volume, no change. Took out RAM modules one by one. Problem disappeared. A RAM module flaked out after 14 months. Future Shop refused to honour the manufacture's lifetime warranty, because I had not purchased an extended warranty. (why would you buy an extended warranty when the product comes with a lifetime warranty?) Mobel has sent me a RMA for the RAM. Lesson learned. Hope this helps someone.
