How to reset bios: The BIOS is the Basic Input / Output System that gets your computer running before Windows, Linux or MacOS starts. That is, it is the firmware on your motherboard that makes everything happen. BIOS settings can be changed to adjust low-level system hardware settings, enable or disable boot devices, add password protection to your computer, and apply other settings.

Like any configurable part of your computer, the BIOS can become corrupted. You can make inadvertent changes that destabilize your system, be malware victims or a failed BIOS update or power outage, or just forget your BIOS password. In these cases, restoring the BIOS to its default settings can restart it.

If you experience problems when you try to install Windows 10 from a USB device or DVD, it may also help you to reset the BIOS. In this article, we’ll take a look at a couple of ways you can reset your BIOS back to its original factory state, otherwise known as clear CMOS cache.

How to reset bios: Clear the CMOS cache on a PC

Due to the variety of makes and models, this guide is far from exhaustive, but the basic principles for accessing the BIOS or UEFI firmware interface can be found in our BIOS Setup Guide.

Finding the setting to reset your BIOS will vary depending on your computer. On my HP desktop and notebook PC, the reset function is located in the File -> Default Settings menu and is called Restore Factory Default. Users should search for words related to the default restore or factory settings. Usually, you will have to press the F10 to confirm the changes before leaving.

Another way users can reset their BIOS defaults is by manually resetting a jumper on the system board. When I first started working as a systems administrator at a local high school, students would enter the BIOS and set up a password to block other students. Resetting the jumper on the motherboard and applying a standard BIOS password to access to prevent access solved this problem.

Before you start, make sure your computer is turned off, the power cord is unplugged, and wait about 30 minutes for the system to cool. Why? There may still be an electrical charge, even when it is off and disconnected. You do not want to risk any possibility of electric shock or damage to components.

Proceed to open the system drive then look for a small jumper – there may be two: one to reset the BIOS and one to only the BIOS password. Remove both, reconnect the system unit to alternating current, start the system and wait about 10 minutes. Once your BIOS has been reset, reconnect the jumpers, then close the system drive, reconnect the external devices, then turn on the system.

On my HP desktop, the CMOS bridge is actually a button, you simply press and hold for about 5 seconds. Therefore, this process varies depending on the make and model of your computer.

Another method that users can try is simply to eliminate the CMOS battery itself. The CMOS battery looks like a small silver coin.
