Or you could try to go to start - control panel - mouse and check out the settings in there. Might include the touch pad in the settings or tabs.

First, turn on (or restart) your computer. When the Dell logo comes up

press F2 to open the bios setup program.



Press Alt-p three times to get to page 4. Near the middle of the

screen you should see an option called Pointing Device. Change it from

Touch Pad - PS/2 Mouse to just PS/2 Mouse (this should work fine for

your USB mouse). Then press ESc to exit the bios, making sure to save the changes.
