Thank you for your enquiry. Checking the Asus Web Site
The system could be using the on-board video o PCI Card.
If you are using the on-Board you can find the latest drivers on https://www.asus.com/Motherboards/H81MA/HelpDesk_Download/
Or you can also try our latest driver https://downloadcenter.intel.com/product/81496/Intel-HD-Graphics-4600-for-4th-Generation-Intel-Core-Processors
But will highly recommend you to first contact Asus to verify if they have encounter any problem and to also update the BIOS on the motherboard.
