The BIOS is basically the program your processor runs when you turn your PC on to start and sync the various peripherals on your PC including your keyboard, Mouse, Video Adapter, and memory. The BIOS on your PC typically comes in an EPROM chip. Electronics and Computer engineers would be aware of the fact that an EPROM or Electronically Programmable Read only memory can only be written on once.
However, you still can update the BIOS on your PC. It is highly recommended you avoid it if you can, especially if you aren’t that comfortable handling computers – Muck it up, and you risk turning your PC into basically a very expensive paper-weight. Without a BIOS, you cannot boot your PC. Even If you are able to boot it, you may face issues with the display, your PC may shut down erratically, The list is endless.
However, you may run into a situation where you may need to update your BIOS; mostly due to a hardware problem. In that case, you can use this guide to take you safely through the process of updating your BIOS on your PC.
Step 1: Plug into an uninterrupted Power Supply
Most people forget this first crucial step. Plug into an uninterruptible power source even if you are using a laptop. If your laptop or PC shuts down midway, you might as well wave your laptop bye-bye or better, take a hammer and break it to pieces (Relax, there still are ways to recover it, but you don’t want to go there)
Step 2: Check your BIOS version
You can do this by pressing the start button, which is at the bottom left a corner of your screen by default. In the search box, type in system information. Open the system information desktop app. On your Windows 10 PC, you should be able to the BIOS version. Note that down.
Alternately, you can start command prompt and enter the following command:
wmic bios get smbiosbiosversion
Step 3: Backup your BIOS
If you are using a BIOS loader from a third party manufacturer or your motherboard supplier, there should be an option to backup your BIOS.
Step 4: Visit your Motherboard manufacturers website
Your BIOS is unique to the manufacturer of your motherboard. Check out the Support page or the download page and locate your motherboard on there. You can download the most updated version from there
Step 5: Download the BIOS file
Once you locate your specific motherboard on the manufacturer’s website, download the ZIP or RAR file of your BIOS and extract its contents into one folder.
Step 6: Make sure you clearly read the attached documentation
Included in the ZIP folder, you should find a text document that basically lists down all the improvements the manufacturer has made over previous versions of the BIOS. The most important things to note are OS specific information; Do you need run a patch just because your PC is still running windows XP, Do you need to update a specific driver, stuff like that.
Step 7: Update your BIOS
Now, this step actually depends on whether you have an old PC or a new one. For newer PCs, it’s actually pretty easy. Modern Motherboard manufacturers release .exe files of their BIOS updates. Simply run it after closing all your applications and wait for it to work its magic. Reboot the PC once you are done. Just make sure that your PC doesn’t turn off.
On the other hand, If you have an old PC, it’s probably going to take a while. You have to first create a bootable drive on a DVD or Pen-Drive. There are a lot of tools available to help you convert your HDD or Pendrive into a bootable disk like Rufus.
Copy the BIOS file onto your pen-drive, Reboot your system but this time, boot from your pen-drive. Wait for your BIOS to update and Reboot your PC again
There is a third way to update your BIOS as well. Your Motherboard manufacturer may have a utility to update your BIOS. Asus Motherboards have a BIOS update utility called EZ flash. It automatically detects the BIOS file and updates it for you. You can even Backup your existing BIOS in case you run into some trouble.
As a rule of thumb, though, try to avoid fiddling with the BIOS. If need be, though, with these steps, you should be able to update your BIOS no problems. Just make sure you follow each step to the word and take care that your laptop does not go bust while you are updating your BIOS. Trust me on this.
