High I'm only a novice, but assuming its the XP programmes and not the
internet running slowly you first could try disk clean up and defragging all
your files this might unclog and help to run faster or your computer might
not have sufficient memory left to go faster - somewhere in systems
information you should be able to find out how much space is left available
to use and or try deleting a load of unused files/programmes etc this helps,
Also run Virus programme incase you have a virus or it might be (Using
internet) a busy time of day and to many users already on the net. I found
this when I had dial up, but not on 4MB high speed broadband which is
excellent. Hope I have helped a bit
