I've had this problem with bad ram. So at least best to check the RAM thoroughly. It also sounds like a dud battery. (Maybe - but you may want to check on this wild advice - If the standard battery is too expensive to replace, buy 3 nicads of whatever size for cheaper and hook them up. Maybe you have some around for torches and stuff. Keep them in good charge. Swapping them out for another set without breaking the power is simple, put the replacement power in parallel and unhook the set needing charging. Depends on what you have lying about... I seem to always have the standard ones about from dismembered old Macs - if anyone throws one out, at least grab the battery) If you clean install again, put a diagnostic like Norton's thru your hard disk, defrag it, have spare space for VM, rebuild desktop with TechTool Lite, press cuda buttons, chuck out preferences, run with a base extension set... But first get a decent battery set up and check RAM. (BTW, these days, 128 is not a lot when using 9.0.4 though this is unlikely to be the real source of so many error messages...)
