I agree with most of the consensus here - the problem is Windows ME. It has a built-in "feature" that randomly causes problems on the computer it is installed on -- ok, not really, but everyone I have talked to or heard of that uses ME says that it gives nothing but mysterious problems. You would be better off by installing a fresh copy of a new OS. I know that is not a very technical answer, but as you can see - most people are telling you the same thing! Good luck anyway.
