Hi sohom,

Last part of the video suggests updating the System Setup (BIOS) using an external monitor. Have you updated the BIOS? If no, please download and update the BIOS.

Note: Plug your computer to a good, working UPS before you update the BIOS. If you experience a loss of AC power or a significant voltage sag/spike during the BIOS flash, you will either have to buy a new BIOS chip or buy a new motherboard.

You can watch this video on how to update the System Setup:
