To be totally honest frank, forget all that stuff.
save anything important on to cd or tape, then do a complete format mate, it's the best way to clear all that rubbish away, and get a fresh system.
Just finished doing a total format and reinstall of my 6 home systems.
I was'nt really going to do it, but have just upgraded my whole home network to a gigabit network, so made sense to have all the the systems running fresh and clean.
The Improvement has been incredible, and thats just with out have all the clutter on the systems, gigabit with broadband is excellent.
cheers
