How To Fix Black Screen After BIOS Update?

The Basic Input/Output System (BIOS) of your computer should always be up to date. This can make it more secure, compatible, and fast. But it can sometimes give you problems you didn’t expect, like the dreaded black screen. It can be very scary when this happens because it looks like your computer won’t work or react. There are several reasons why you might see a black screen after updating your BIOS. This full guide will explain each one and show you how to fix the issue step by step.

What is BIOS?

An important piece of software on your computer is the BIOS. It sets up and controls how the operating system and devices use and talk to each other. It sets up your gear and starts up your computer, among other important tasks. When you update the BIOS, you can get rid of bugs, make the computer work better with other gear, and add more security. But it’s very important to do what you need to do to stay out of trouble.

Common Causes of Black Screen After BIOS Update

  • Too Little of an Update: If you get a black screen, it’s likely because the BIOS update process is not finished. This might happen if the power goes out during the update or if the file for the update is broken. To escape these kinds of problems, make sure the power source is stable and look for mistakes in the BIOS update file.
  • Bugs in the BIOS: If you update the BIOS, the settings may go back to the factory settings, which might not work with the way your system is currently set up. This could go wrong and lead to a black screen.
  • Conflicts with Hardware: New BIOS versions might not be able to connect to all of your system’s hardware. This is especially true for older systems since brand-new software might not work with old hardware.

Initial Troubleshooting Steps

  • Making Sure the Computer Has Power and Safe Connections: Before you move on to more in-depth analysis, make sure your computer has power and the safest connections. The power cords should be unplugged and plugged back in several times, and there should be no weak connections.
  • Putting back the settings that were there before the BIOS update: If the update changed your settings, you may need to put them back the way they were. Changing the boot order, SATA configuration, and built-in devices can help fix problems with compatibility. To get to the BIOS setup, press a key like F2, F10, Del, or Esc during startup.
