Option 2 – Automatically (Recommended) – If you don’t have the time, patience or computer skills to update your video driver manually, you can, instead, do it automatically with Driver Easy. Driver Easy will automatically recognize your system and find the correct drivers for your exact GPU, and your Windows version, and it will download and install them correctly:

2. Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
   
3. Click the Update button next to the flagged graphics driver to automatically download the correct version of that driver, then you can manually install it (you can do this with the FREE version).
   
   Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system. (This requires the Pro version which comes with full support and a 30-day money back guarantee. You’ll be prompted to upgrade when you click Update All.)
