Hi,

Please do try to uninstall/reinstall the graphics card driver that maybe the cause of that issue.
- Go to Device Manager and uninstall the graphics card driver.
- Open Programs and Features and uninstall anything related to your graphics card.
- Download and install the latest driver from the graphics card manufacturer.
NVIDIA: nvidia.com/download/index.aspx
AMD: http://support.amd.com/en-us/download
- Once installed reboot your laptop then test it again.
- Also do check the manufacturer site of your PC for any updates or hotfixes that may help.
