You did not give your model number nor full system specs so it is hard to know what you have.
If you have an AMD APU make sure you are downloading the APU driver, not the graphics driver.
If your laptop maker has a current driver you are best to use their driver as it may contain optimizations for your model.
Once you have the correct driver do the following and it should get you going.
Have the driver you want to install downloaded.
Run DDU from wagnardsoft dot com, from safe mode with the Internet disabled. Just unplug or turn off the router or modem is fine.
Restart after running DDU to normal but still have the Internet disabled.
Then install the driver again don't use express settings. Use Factory Reset and that should get you going again.
Good Luck!
