PS/2 for the win.

It never lets me down.

Well, it does have the disadvantage that it's not hug and pray: it only
gets detected at boot (at least I've never found a way to plug one in
after boot and have it seen).

USB always has some little surprise waiting for you.
Some corner condition, like detection not working or
something. Whatever magic smoke is in PS/2, it's
damn good.

I certainly use it if there is a socket for it - especially on older
machines (which, sadly, probably means anything with a PS/2 socket at
all these days, as they seem to be being dropped): (a) it uses a socket
which otherwise isn't being used, (b) it _doesn't_ use up a USB socket
(which were in short supply on older machines, though these days they
seem to have them coming out of their ears).

[I recently helped a friend set up a new motherboard (the processor had
fried on the old one, and socket damaged in removal); it had a single
PS/2 socket, which was coloured half green and half purple. We ordered a
Y cable, but never did get the mouse working (the keyboard worked,
either plugged directly into the socket or via the Y cable; we never
tried the mouse directly into the socket) - we eventually gave up and
just used a USB mouse. (Both had been OK with the previous mobo.) I
suppose the Y cable _could_ be faulty. Windows 10. Being a fairly modern
mobo, it had plenty of USB sockets.]

I use a KVM, or rather two 4-way KVMs chained in series, to work the 5
PCs, and the KVMs only have USB connectors.

Ah. Maybe you can use a PS/2 keyboard with that one machine (i. e. not
connect the keyboard part of the KVM to it).

I also recall some complication with the A10 address bus line in the
early 16-bit DOS PCs being used to switch something or other.

(Pun intended) Memory failure! It was the A20 address bus line! From
p170 ...
"The Undocumented PC", Frank van Gilluwe, 2nd Ed'n, 1997
Addison Wesley, 0-201-47950-8

"The basic AT design, still in use today, has an option to turn off
the A20 address line externally from the CPU. This is the default way
the system powers up, and it normally remains this way while real mode
is active. This emulates the original 8088 so that addresses above
1MB will wrap back to low memory."

This is a screenshot of an ancient text-format legacy memory map that
I created way back when I was trying to get my head around this sort
of thing (screen shot because modern ANSI text editors don't display
the DOS line characters properly):

We've moved well OT for your problem, for which, apologies. To get
back to that, I think you need to check the following:

A) As the discussion has already highlighted, the above figures don't
look right for W7 - I'd expect that ...
Total Virtual = Total Physical + Page File
.... so check your virtual memory settings via:
rt-click My computer
Properties
Advanced
Performance Settings
Advanced
Virtual Memory

Many would leave this on System managed, but if that's what is set
now, and it's not working satisfactorily, consider setting it
manually. Opinions vary, but IME the usual setting is a minimum equal
to the actual PC RAM, and a maximum of double that (you may note that
some of my own machines don't follow that for legacy reasons too
irrelevant to go into here). If changes are made, a reboot will be
required.

B) That there is no malware present. Run Task Manager -
Ctrl-Alt-Del, Last menu option - and check for suspicious
processes running. You can also use this to find out what is hogging
the CPU, click on the column of that name, and see what processes have
the highest numbers, also click CPU Time and check which processes
have consumed the highest percentage of CPU time. Then do a malware
scan using something with a solid reputation such as Malware Bytes
Anti-Malware. What AV software are you running? It may be running a
complete scan on boot up, which may be what is causing the thrashing.

C) That there is no unnecessary software being launched from the
following locations:

1) Startup Folders:

Start, All programs, Startup

.... which is a runtime merging of the following directories ...

The All Users Start Menu:
C:\ProgramData\Application Data\Microsoft\Windows\Start
Menu\Programs\Startup

.... and ...

The User Start Menu:
C:\Users\UserName\AppData\Roaming\Microsoft\Wind ows\Start
Menu\Programs\Startup

2) Registry Keys:

HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Run
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Run
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Run

3) Legacy locations (unlikely, but nevertheless check them to be
sure):

C:\CONFIG.SYS (is normally zero length these days)
C:\AUTOEXEC.BAT (ditto)
%WinDir%\System.ini
%WinDir%\Win.ini

D) Check that updates are up-to-date, if not, do them all, and then
see if the thrashing continues.
