Both my desktop and laptop machines are fully updated with XP update files
but recently they have both started experiencing the same problem.
Frequently, everything freezes for a second or two before resuming as if
nothing has happened. Is this something to do with service pack 3?

On 4/22/08, Microsoft showed the update gold shield telling us to
download/install and update. I proceeded to use Microsoft Update and the
system scanned our laptop Acer Aspire AMD base.
After a long wait it inform us that we had the SP3 to be installed.
