interesting comments,which i will look into.
but will say that i ran xp pro on a dell piii 667 mhz processor for around three or four years succesfully, the other piii processor is set at 800 mhz and it runs at 100% for those five mins so perhaps thats what i should be looking at.
i want to find out why its doing what its doing as much as fixing it for future reference
as ive noticed its a fairly common problem

If you want to know everything that's running...
I suggest Mark Russinovich's Process Explorer

the problem is now fixed,it appeared to be a left over part of a programme called memory optimizer,which was useless anyway.
now this pc flys any offers?

lol glad to hear it.

It can be a good idea to run a registry-cleaner-- or manually edit the registry-- I usually just go in, find the install-folder(s) for apps I really disliked, delete it and reboot.

i use revo uninstaller on the main pc which clears out leftovers that win add remove doesnt see
