If you did not ERASE the hard drive and perform a FRESH XP install, that's your problem.
Windows ME was also known as the Mistake Edition and did not play well with others.
It is also not a good idea to have 2 memory DIMM's of different size installed on the motherboard.

Actually I have 3 memory DIMMs: 2 64-mb and 1 512-mb. I suppose I could get another 512 and throw out the 2 64s.

As for erasing the hard drive, there’s a lot more stuff on that thing than Windows ME files. I would hope there’s a way to clean up things without erasing everything.

Just curious, why would memory DIMMs of different sizes hurt the computer?
