Keyboard doesn't work (by 4 users)

Several times, on this brand new Gateway, the keyboard fails to function. None of the keys work, and the lights (as on Num Lock) are not lit. On the Control Panel the "Keyboad" is not listed. Something has removed the Keyboard Driver. This has happened three or four times.

The keyboard that came with the computer has a serial port connection.

After rebooting a couple times, because of Plug and Play, the keyboard again functions.

Help remove the frustration.

Thank you.
