Are you sure your processor is not 1.90 GHz (rather than 1.09 GHz)?
My XP 2700+ is 2.16 GHz so yours would be a bit lower. Remember that AMD use the "equivalent" speed, or whatever you want to call it, so a 2600+ does not have a clock speed of 2600.
Sorry if you know this and you are actually getting 1.09...if so I can't help!
Also, I wonder why you need to keep re-activating. If you say what your other problems are, some of the clever souls on this forum may be able to suggest ways to make your system more stable.
