If I remember correctly, a utility named memtest exists, to test the
system RAM. If a utility exists, as suggested, named disks , does a
utility exist, that goes through and checks each peripheral device for
both the driver and hardware functionality?

Whilst the above message suggests possible/probable hardware failure,
because the problem involves both the computer's built in trackpad and
keyboard, and, the external mouse and keyboard (connected via USB and
wifi, through a plug in USB wifi adaptor, I wonder whether something
like a driver, or, interrupt handler, has been corrupted.
