I've had XP installed for about 2.5 years and have kept it up to date

Despite this, I am getting more and more 'blue screens' without a
consistent cause, so it seems that a clean install is called for. But,
as all updates have been done automatically, I have no CDs etc to
provide the updates, which must, by this time, amount to hundreds of
Mb.

Perusal of the Windows folder offers plenty of opportunities to
uninstall various updates, but I can't see any 'update' files or
folders.

Is there a way to save all the updates before formatting and
reinstalling Windows?

You can contact Microsoft and they will provide a copy of SP2
on CD for free or you can download it from their site. It includes
all previous fixes. That said, it's usually not necessary to do
a reformat and reinstall. What error messages are you getting
when you get the BSOD?
