Open Command Prompt, type “wmic bios get smbiosbiosversion” in the window và hit Enter to kiểm tra your BIOS version. Consult the documentation for your specific PC or motherboard on the manufacturer’s website for instructions on how to download and install the latest BIOS version.
You probably shouldn’t update your BIOS, but sometimes you need to. Here’s how to check what BIOS version your computer is using and flash that new BIOS version onto your motherboard as quickly và safely as possible.

Be very careful when updating your motherboard’s BIOS! If your computer freezes, crashes, or loses power nguồn during the process, the BIOS or UEFI firmware may be corrupted. This will render your computer unbootable — it’ll be “bricked.”

How to kiểm tra Your Current BIOS Version in Windows

Your computer’s BIOS version is displayed in the BIOS setup menu itself, but you don’t have to reboot to check this version number. There are several ways to lớn see your BIOS version from within Windows, và they work the same on PCs with a traditional BIOS or a newer UEFI firmware.

Check Your BIOS Version at the Command Prompt

To kiểm tra your BIOS version from the Command Prompt, hit Start, type “cmd” in the tìm kiếm box, and then click the “Command Prompt” result — no need to run it as an administrator.


At the prompt, type (or copy và paste) the following command, and then hit Enter:

wmic bios get smbiosbiosversionYou’ll see the version number of the BIOS or UEFI firmware in your current PC.


Check Your BIOS Version by Using the System Information Panel

You can also find your BIOS’s version number in the System Information window. On Windows 7, 8, or 10, hit Windows+R, type “msinfo32” into the Run box, and then hit Enter.


The BIOS version number is displayed on the System Summary pane. Look at the “BIOS Version/Date” field.


How to lớn Update Your BIOS

Different motherboards use different utilities & procedures, so there’s no one-size-fits-all phối of instructions here. However, you’ll perform the same basic process on all motherboards.

First, head khổng lồ the motherboard manufacturer’s website & find the Downloads or support page for your specific mã sản phẩm of motherboard. You should see a list of available BIOS versions, along with any changes/bug fixes in each and the dates they were released. Tải về the version lớn which you want to update. You’ll probably want lớn grab the newest BIOS version — unless you have a specific need for an older one.


If you purchased a pre-built computer instead of building your own, head to lớn the computer manufacturer’s website, look up the computer model, và look at its downloads page. You’ll find any available BIOS updates there.

Your BIOS tải về probably comes in an archive — usually a ZIP file. Extract the contents of that file. Inside, you’ll find some sort of BIOS file — in the screenshot below, it’s the E7D14AMS.291 file.

The archive may also contain a README or other text file that will walk you through updating lớn the new BIOS. You should kiểm tra out this tệp tin for instructions that apply specifically to lớn your hardware, but we’ll try lớn cover the basics that work across all hardware here.


RELATED: What You Need to Know About Using UEFI Instead of the BIOS

You’ll need to lớn choose one of several different types of BIOS-flashing tools, depending on your motherboard & what it supports. The BIOS update’s included README file should recommend the ideal option for your hardware.

Some manufacturers offer a BIOS-flashing option directly in their BIOS, or as a special key-press option when you boot the computer. You copy the BIOS file to a USB drive, reboot your computer, and then enter the BIOS or UEFI screen. From there, you choose the BIOS-updating option, select the BIOS file you placed on the USB drive, & the BIOS updates to lớn the new version.

You generally access the BIOS screen by pressing the appropriate key while your computer boots—it’s often displayed on the screen during the boot process and will be noted in your motherboard or PC’s manual. Common BIOS keys include Delete and F2. The process for entering a UEFI thiết đặt screen can be a bit different.


There are also more traditional DOS-based BIOS-flashing tools. When using those tools, you create a DOS live USB drive, & then copy the BIOS-flashing utility and BIOS file to that USB drive. You then restart your computer and boot from the USB drive. In the minimal DOS environment that appears after the reboot, you run the appropriate command — often something lượt thích flash.bat BIOS3245.bin — and the tool flashes the new version of the BIOS onto the firmware.

The DOS-based flashing tool is often provided in the BIOS archive you tải về from the manufacturer’s website, although you may have to download it separately. Look for a file with the .bat or .exe tệp tin extension.

In the past, this process was performed with bootable floppy disks and CDs. We recommend a USB drive because it’s the easiest method on modern hardware — a ton of modern computers don’t even have CD or DVD drives anymore.

Some manufacturers provide Windows-based flashing tools, which you run on the Windows desktop khổng lồ flash your BIOS & then reboot. We don’t recommend using these, and even many manufacturers who provide these tools caution against using them. For example, MSI “strongly recommends” using their BIOS-based thực đơn option instead of their Windows-based utility in the README tệp tin of the sample BIOS update we downloaded.


Flashing your BIOS from within Windows can result in more problems. All that software running in the background — including security programs that may interfere with writing lớn the computer’s BIOS — can cause the process khổng lồ fail & corrupt your BIOS. Any system crashes or freezes might also result in a corrupted BIOS. It’s better lớn be safe than sorry, so we recommend using a BIOS-based flashing tool or booting lớn a minimal DOS environment to flash your BIOS.


That’s it — after you run the BIOS-flashing utility, reboot your computer, and the new BIOS or UEFI firmware version loads. If there’s a problem with the new BIOS version, you may be able khổng lồ downgrade it by downloading an older version from the manufacturer’s website and repeating the flashing process.
