I apologize if this has been answered before, but I recently acquired a Power Mac G4 and it is freezing after being put to sleep. I put a new PRAM battery in it (which now ensures that it keeps the time and remembers my wi-fi connection passwords), but it is now inevitably freezing about 2-3 minutes after being put to sleep. It's really frustrating! The sleep functionality and ease of use is one of Mac OS's top selling points imo, so I would really like for this to work flawlessly. What are my options? I've also reset the little PMU button inside the machine, so between resetting the PMU and getting a new PRAM battery, I don't know what could be causing this.... HELP!
