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