There is a party trick I have seen some of these play where they
throttle back to a very low clock speed all the time. Going into the
BIOS and resetting to default BIOS settings will fix that one. (might
also be worth checking for BIOS upgrades while you are at it).

Having said that, its a slow machine to start with. About the only thing
you can do to make any real difference would be to clone the HDD onto a
SSD.

It has Win10 installed on it, it seems to have a reasonable spec. I'm
wondering if there should be a recovery CD for it, or if anyone knows
where I could download from and burn a CD?

It will have a recovery partition. So you can recover to the supplied
image (which is unlikely to be Win 10).

Failing that you can download Win 10 from MS - just search for download
Win 10. That will get you the media creation tool which will either
upgrade the machine its being run on, or let you write a boot image to
USB or DVD.

For the utilities etc, there will likely be a tag number of some kind on
it that you may be able to use on the Lenovo web site to take you to the
right set of utilities.

Why do machines with fast multi-core processors end up being unbearably
slow?

Mostly something program wise thrashing around
in the background using up lots of cpu resources.

The reasons must be known

Yes they are.

and easily fixable.

Can be a bit less easy with the worst of it when
you cant even run decent diagnostics because what
is thrashing around using up all the cpu resources
means that you cant even run the diagnostic and
they dont necessarily show up on the task manager.
