Updating our files
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 to 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 the computer manufacturer’s website, look up the computer model, and look at its downloads page. Your BIOS download probably comes in an archive—usually a ZIP file. Inside, you’ll find some sort of BIOS file—in the screenshot below, it’s the E7887IMS.140 file.
The archive should also contain a README file that will walk you through updating to the new BIOS.
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.
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.
You can do this by clicking on the More Options tab at the top and selecting "Clean up" under System Restore and Shadow Copies.
Step 2: Make sure to check the box next to Windows Update Cleanup and any other files you would like to clean (honestly, all of them) and click OK.
Now Disk Cleanup is deleting all of the files for each selection that was made.
The DOS-based flashing tool is often provided in the BIOS archive you download from the manufacturer’s website, although you may have to download it separately. In the past, this process was performed with bootable floppy disks and CDs.
We recommend a USB drive because it’s probably be the easiest method on modern hardware.
