Method 1: Remove accessories and update BIOS
  • Remove the accessories, including the keyboard, mouse, external hard drives, printers, memory cards, discs from the optical drive, as well as any adapters in card readers, and similar peripherals. Sometimes, external devices may prevent your system from functioning properly. 
    Note: Please disconnect all external monitors as well. For desktop computers, connect only one external monitor initially to verify that the system can boot and display properly.
  • Update BIOS to the latest version. Here you can learn more about How to Update BIOS with ASUS Firmware Update/EZ Flash. (For desktop products, please refer to ASUS Motherboard EZ Flash 3 Introduction.) 
    Note: Please use another PC to search and download the BIOS on the ASUS support site for the defective model, then copy the BIOS into a USB drive. If you have no other PCs, USB drives, or the BIOS has been updated to date, please ignore this step.
