On Start , search for Device Manager, and select it from the list of results. Under Mice and other pointing devices, select your touchpad, open it, select the Driver tab, and select Update Driver. If Windows doesn't find a new driver, look for one on the device manufacturer's website and follow their instructions.

If those steps didn't work, try uninstalling your touchpad driver: open Device Manager, right-click (or press and hold) the touchpad driver, and select Uninstall. Restart your device and Windows will attempt to reinstall the driver.

If that didn't work, try using the generic driver that comes with Windows. Here's how: in Device Manager, right-click (or press and hold) your touchpad driver > Update driver software... > Browse my computer for driver software > Let me pick from a list of device drivers on my computer, select HID compliant mouse, select Next, and follow the instructions to install it.

If changing your driver doesn’t help, there may be a problem with the touchpad itself. Contact your PC’s manufacturer for help.
