On Windows 7, you can search the Start menu for System Information to find it.
On Windows 8, it’s more hidden — but you can still launch the System Information panel on Windows 8.
This will render your computer unbootable — it’ll be “bricked.” 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 see your BIOS version from within Windows, and they work the same on PCs with a traditional BIOS or a newer UEFI firmware.
To use a command, open a Command Prompt window — press Windows Key + R, type cmd into the Run dialog, and press Enter.
Run the following command: You can also find your BIOS’s version number in the System Information window.
First, head to the motherboard manufacturer’s website and find the Downloads or Support page for your specific model 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. You’ll probably want the newest BIOS version unless you want an older one for a specific reason.
If you purchased a pre-built computer, head to the computer manufacturer’s website, look up the computer model, and look at its downloads page. Your BIOS download probably came in an archive — usually a file. You’ll find some sort of BIOS file — in the screenshot below, it’s the E7887IMS.140 file.
If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware.
If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices.
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 and safely as possible. If your computer freezes, crashes, or loses power during the process, the BIOS or UEFI firmware may be corrupted.
