This behavior can occur if your DirectX video driver is damaged or incorrectly installed.
To resolve this issue, follow these steps:
Download the current version of DirectX.
Right-click the desktop, and then click Properties.
Click the Settings tab, and then click Change Display Type or Advanced Properties. Note the name of your display driver.
Click Change in the Adapter Type section, and then click Show All Devices.
In the Manufacturers box, click Standard Display Types.
In the Models box, click Standard Display Adapter (VGA), click OK, and then click Close.
Click OK twice.
Click Yes if you are prompted to restart your computer.
Reinstall DirectX.
