please describe the steps how to uninstall it.Try using the DDU or Display Driver uninstaller in safe mode to remove gpu driver. This will also remove any corruption caused by previous driver installs.
See if the driver from your laptops support page functions any better:

i did what you said and i reinstalled the driver from hp website for my model. there was an improvement in the speed but the screen keeps tearing when i opened the games. could it be the newer version of the driver that is causing the tearing? i remember updating the driver about two months ago.Download your new gpu driver or use the same one again. ( Just so you have the driver ready to install when needed)
Download the DDU:
Display Driver Uninstaller (DDU) V17.0.8.6 Released. - Wagnardsoft Forum
Unzip the DDU to your folder of choice and then boot into safe mode:
How to Boot Into Safe Mode on Windows 10 or 8 (The Easy Way)
Once in safe mode, right click the DDU icon and run as administrator.
After the DDU opens you want the top option: Clean and restart.
Once your back in windows install your new or existing driver.
If your machine keeps installing a driver from Windows update before you have time to install the version you downloaded then disconnect from the net until the driver is updated the way you want and not Microsoft's way.
Post back with any questions or problems.
