Have you forgotten your BIOS password and need help resetting your PC BIOS? You're not alone. Luckily, there are dozens of ways to reset BIOS to default settings. In simpler words, you can reset BIOS by following the instructions mentioned in this article.

What Is BIOS & Why Need to Reset It

BIOS stands for Basic Input/Output System. It's the first layer of software that gets loaded onto a computer's main RAM chip and loads up the rest of your operating system. This means BIOS is responsible for nearly all the issues of your PC, which makes it so important to rest your BIOS.

Moreover, BIOS allows you to install and configure hard drives, RAM, and sound cards.

Since BIOS is responsible for running the operating system, it's essential to keep it up to date. The more often you update your BIOS, the better your computer will run.

How to Reset BIOS to Default Settings in Every Possible Way

Whether it's configuring your computer's hardware settings or monitoring screen resolution, resetting BIOS is the ultimate solution to every problem. However, you will also want to ensure that you've updated your BIOS with all relevant updates before you restart your computer or install new hardware so that everything works together.

Solution 1. Reset BIOS Using BIOS Setup Utility

If your computer goes wrong, you should first check if the power supply is working. If it works properly, try resetting the BIOS using the BIOS Setup Utility.

To reset the BIOS using BIOS Setup Utility:

1. What happens if I reset my BIOS to default?

BIOS is the first thing that boots up when you turn on the computer. It contains a lot of settings for things like your graphics card, your hard drive, and other components. If you reset your BIOS to its default settings, it will be like starting over from scratch. Some computers have a button that can do this, but some only allow you to change the settings by going through software menus.

2. Will resetting BIOS delete the files?

The short answer is no; resetting your BIOS will not delete any files from your system. The reason for this is that the file systems used by most operating systems are completely different than those used by BIOS and firmware applications like CPU microcode updates, which are often updated with new features and bug fixes that require updating.

3. What is BIOS recovery?

BIOS recovery is restoring an older version of firmware, which can be used on newer hardware or software versions. This feature is available on some motherboards and makes it possible for users to update their system's firmware without reinstalling everything from scratch or losing data during an upgrade process called "flash back." Some models even allow users to perform multiple flashbacks at once! This can save time and money while also ensuring that all data remains intact after every update.

4. Does updating BIOS delete everything?

No, updating your BIOS will not delete everything. If you have a computer running off of a hard drive, you can update the BIOS anytime. However, if you are using an SSD or other type of solid-state storage, then there is no need to update the BIOS unless you want to upgrade it.
