First, try restarting your graphics driver:
Press Windows key + Ctrl + Shift + B
If that does not work...
Press Windows key + X
Click Device Manager
Expand Display adapters
Right click the current display adapter
Click Properties
Click Driver tab
Click Rollback driver if the option is available
If not
Right click the current display adapter
Click Uninstall
Check the box that says, "Delete the driver software for this device.”
Exit Device Manager
Restart
Go to Start -> Settings -> Update & security, then Check for updates and install any available updates.
You might need to update the display driver from the manufacturer of your computers website.
If you have an nVidia, AMD ATI video card or Intel HD graphics installed, you can download the latest drivers from their website.
First, determine what type of graphics you have installed.
Press Windows key + X
Click Device Manager
Expand Display adapters
Once you have determined the graphics driver, go the vendors website and search for the driver in the download section:
Intel - Downloads for Graphics Drivers - Drivers & Software - Intel

nVidia - http://www.nvidia.com/Download/index.aspx
AMD ATI - Download Drivers - AMD Support
http://support.amd.com/en-us/download
Some of these sites offer autodetect options.
