Welcome to Seven Forums. You may want to follow this driver guide to install a modded driver for your laptop as some manufacturers modify their .inf files for their graphics cards.
The mod tool can be found at the bottom of the page.
Once you have modded the graphics driver you may want to go to device manager>display adapter> update driver software>browse my computer> have disk> browse to where you have the driver file located and install from their by clicking the setup.exe file. If this won't work you might want to try following the same steps then click or double click the .inf file.
