One more time, I switched to a USB Keyboard and Mouse and now I get the
i8042 prt error showing up in the Event Log. I have looked for a solution
(turn off the service?) and cannot seem to find a straight forward
explanation on how to stop the error. I would suspect that a whole bunch of
computers log this error and don't quite understand why the fix is hidden -
at least from me. A little help would be appreciated.

You could try this...

Click Environment Variables... button (near buttom of dialog box)
Under System variables Click New... button

and

Type in devmgr_show_nonpresent_devices for Variable name:
Type in 1 for Variable value:

Click OK to close New System Variable box
Click OK to close Environment Variables box
Click OK to close System Properties box


Open new instance of Computer Management
Right-click on Computer
Select Manage
Click on View
Select Show hidden devices

Expand Keyboards and delete greyed out keyboard associated with PS/2 port
Expand Mice and other pointing devices and delete greyed out mouse
associated with PS/2 port

Close everything and reboot.


I didn't test this thoroughly and I might have missed something.

My recommendation is just ignore it. It just means it didn't detect a PS/2
keyboard/mouse that used to be there.
 
Thanks for the response. I'll give it a try - however, your last suggestion
was probably the best solution - ignore it, W7 and a fresh install is only a
few weeks away.
