In the event that this doesn't work then it might be a graphics driver issue. In that case then you will need to make sure that you have the latest driver for your graphics card or integrated graphics. You can find your graphics card by right clicking on the Start Button, going to Control Panel, typing device manager in the search bar, going to Device Manager, and clicking on Display Adapters. From there, if you tell me which brand of graphics card that you have, I can give you further instructions on how to update its drivers.
