10 Reasons Why You Must Update Your BIOS


Your computer’s Basic Input/Output System, or BIOS, is the first software that runs when you turn on your PC. It initializes the hardware and starts the boot process.

Because it’s so important, it’s essential to keep your BIOS up-to-date. Here are 10 reasons why:

1. To Support New Hardware

When you purchase new hardware for your computer, it’s important to check for BIOS updates. The BIOS is a piece of low-level software that controls the basic operations of your computer. In order to support new hardware, manufacturers occasionally release updates to the BIOS. These updates can often be found on the manufacturer’s website. In most cases, updating the BIOS is a relatively simple process. However, it’s important to follow the instructions carefully, as a mistake could render your computer unusable.

If you’re not comfortable updating the BIOS yourself, you can always take your computer to a professional. However, BIOS updates are generally quick and easy, so there’s no need to pay someone else to do it for you. As new hardware is released, manufacturers will often update the BIOS to support it. If you don’t update your BIOS, you may not be able to use that new hardware. For example, if you want to install a new CPU or use a larger hard drive, you may need a BIOS update.

2. To Fix Bugs and Improve Stability

Many computer users don’t realize that their BIOS needs periodic updates to ensure smooth and reliable operation. The BIOS, or basic input/output system, is a key component of your computer’s hardware that controls the lowest-level operations of the machine.

A BIOS update can provide many benefits, including support for new devices, improved compatibility with operating systems, and various bug fixes. For example, a recent BIOS update for a popular laptop brand fixed an issue that caused the computer to crash when the battery was low.

3. To Enhance Features and Usability

In some cases, BIOS updates will also add new features or enhanced functionality. For example, a new version of the BIOS may add support for a larger hard drive or faster CPU.

Updating your BIOS can cut down on boot time, fix compatibility issues, and improve overall performance–or at least it can if done correctly. If you don’t do it right, you risk damaging your computer beyond repair. This is why it’s important to only update your BIOS when it’s absolutely necessary and when you’re positive that the new BIOS will be compatible with your system.

4. To Improve Security

As security threats evolve, BIOS updates will often be released to address them. So if you want to keep your PC secure, it’s important to install any available updates.

One example of a security improvement that can result from updating a computer’s BIOS is the prevention of privilege escalation exploits. Such exploits take advantage of vulnerabilities in the BIOS to gain administrative control of the system. By installing the latest BIOS update, which may include fixes for such vulnerabilities, it is possible to close the door on potential attackers and help to keep the system secure.

Other security improvements that can result from updating the BIOS may include the enablement of new features that provide additional protection, such as boot sector protection or full disk encryption. In short, by keeping the BIOS up to date, it is possible to enjoy enhanced security for the computer as a whole.

5. To Prepare for a Windows 11 Upgrade

If you’re planning to upgrade to Windows 11, it’s a good idea to update your BIOS first. This will help ensure that the upgrade process goes smoothly.

6. To Improve Battery Life on a Laptop

In some cases, BIOS updates can improve battery life. So if you’re using a laptop, it may be worth checking for updates on a regular basis.

In particular, newer BIOS versions often include better power management settings that can help to reduce the amount of power that your laptop uses. As a result, updating your BIOS can be a simple and effective way to give your laptop’s battery life a boost.

7. To Fix Overheating Issues

Overheating is a common issue that can cause a wide range of problems for your computer, from data loss and corrupt files to hardware damage.

If your PC is overheating, a BIOS update may help resolve the issue. In particular, updates that enable better fan control can be helpful.

8. To Improve Gaming Performance

If you’re a gamer, you may be able to get a performance boost by updating your BIOS. In some cases, manufacturers release updates that improve game compatibility or frame rates.

9. To Use Newer Software and Drivers

In some cases, you may need to update your BIOS to use newer software or drivers. For example, you may need a BIOS update to use the latest version of a graphics driver.

10. To Update the Boot Order

If you want to change the boot order of your drives, you may need to update the BIOS. For example, you may want to boot from a USB drive or DVD drive.


These are just a few of the reasons why you may need to update your BIOS. So if you’re having issues with your PC, or you want to use new hardware, be sure to check for updates. In most cases, updating the BIOS is a straightforward process. If you can do it, get in touch with a PC repair technician.
