If your touchpad started misbehaving after you have installed or updated the touchpad driver, it is possible that something went wrong with the driver-installation process. To fix this issue you need to reinstall the driver.

1. Go to the website of your motherboard's manufacturer and search for the touchpad driver (check the don't know how to download and install drivers guide to learn how to download and install the appropriate driver);
   
   
2. When you find and download the touchpad driver, uninstall the previous one in your computer (check the don't know how to uninstall a program / an application guide to learn how to uninstall programs);
   
   
3. Install the new driver you have downloaded;

Note: The best way to uninstall software (in this case, driver) is via uninstaller software. The uninstaller software uninstalls the driver (or software) and performs a thorough scan for leftovers. Sometimes, among those leftovers there are settings that will remain when you install the "fresh" driver and that might cause a conflict again.

The best uninstaller software include Revo Uninstaller Pro, Advanced Uninstaller PRO, iObit Uninstaller, Ashampoo Uninstaller and etc. All you need to do is to install one of them and follow the user-friendly instructions.
