Use an usb mouse to select control panel and then select device management. From there you need to select the mouse and from there select the mouse and right click on it. Select to uninstall the device. Then close all screens and shut down computer. Unplug the usb mouse and restart the computer. If after it completes loading and it doesn't work the you will need a new touch pad. But if it does work it means windows had an corrupt update which caused the problem. Thanks Igor!
Go into the BIOS (F2). Press Alt-P until you reach "Page 4 of 7".
Under "Pointing Device" change the setting from "PS/2-Touchpad" to
"PS/2". Reboot. The touchpad and point stick will still
function as long as there isn't a mouse plugged into the PS/2 port. If
the mouse is plugged in, it will override the integrated devices.
