Thank you, thank you, thank you! You were right! It was the USB keyboard
causing the problems! (Well, I did uninstall SP2, Internet Explorer, and
Windows Media player prior to switching the keyboard.)

Switched keyboard this morning and it worked perfectly!!!!

On motherboards that supply both USB and PS/2 ports, I see no reason to
waste a USB port on the keyboard since a PS/2 port works just as well
for a keyboard. Also, since I can connect to the PS/2 port for the
keyboard, I free up a USB port for another USB device (printer, scanner,
camera, etc.).

Keyboards bought today might be USB-only keyboard. Basically they're
too stingy to include the USB-to-PS2 adapter that comes with other
PS2/USB keyboards.
