Does the problem generate an error message after manually installing the mouse?
Action:
Do the following:
1) Boot from a pure MS-DOS (that is, no AUTOEXEC.BAT or CONFIG.SYS files).
2) Install the mouse driver manually from the Mouse Setup Disk.
NOTE: For the correct instructions on how to install the mouse driver, consult the manual that came with the mouse.
