Resolution

Steps on how to resolve the issue:

Set the BIOS to default settings to see if this resolves the issue. 

  • To access BIOS, press a key during the boot-up process. This key is often displayed during the boot process with a message “Press F2 to access BIOS”, “Press DEL to enter setup”, or something similar.
  • Once in the BIOS Press F9 or the assigned key to automatically load the factory default settings
  • Press F10 to save the changes in BIOS, then reboot.
  • If the issue persist, proceed to step 2.

2.  Check the Graphics settings advanced tab in the BIOS for the option to disable or enable the onboard graphics.  Check the motherboard manual to find this option.

  • Browse the BIOS menu and look for graphics options.
  • Go to the advanced tab
  • Set the onboard graphics or built in graphics to Enable
  • Press F10 to save and reboot. 

The motherboard sometimes disables the built-in graphics by default in favor of the much faster and dedicated graphics card. For more information on this feature, contact your motherboard manufacturer.
