• Right-Click on start button> click device manager> expand display adapters>then select the display drivers that are listed and right-click on it and uninstall the drivers.
• Check the box that states delete the software for this device.
• Then restart the computer and update the bios chipset and graphic drivers from this link: http://hp.com/drivers Please select the country and type the product# of the computer. Then follow the on-screen instructions to update it.(if the drivers are available. Otherwise, proceed to the next step)
