Hey so the over the last week or so I've slowly figured out that the constant kernel panics that have prevented me to sometimes even start up have been from a malfunctioning ram card that was obviously dragging everything else with it when it failed. I finally figured it out by doing the hardware test a few times (first couple of times it didn't show up - ???) and it showed it was a memory failure. I reseated the chips and no dice so I took them in/out and swapped them etc until I found out which one was causing trouble. I'm now running on just 1 card (1gb) awaiting the new one I ordered. The question I guess I want to know is are there any RAM tests you can do periodically that can show a card that's failing? Looking back I now realise that there were probably more beachballs/unexpected quitting than usual before it died. Is there any way to prevent it crashing out of the blue by realising it's slowly dying? It seems like something that should show a warning or something before it completely fails?
