Hi there,
BIOS update is not a common option for all. However you can update your BIOS if you have that kind of opportunity. But first you need to know about your BIOS versions.
So start up your pc and press F2 (if you are using Intel motherboard) or delete (for other motherboard).
Now note your BIOS versions.
Now all you need to find a update of your BIOS versions if available. Then you can update your BIOS from online by these methods.
1. Xpress BIOS update.
2. BIOS flash update.
3. iFlash update.
4. ISO BIOS update.
5. Recovery BIOS update.
Choose the perfect one for you.
Hi jhonnybravo,
Updating the bios is very critical, you can find the updated bios on the manufacturers still suppose you are using HP or Dell laptop the you need to find the bios on their respective websites and while updating the bios you need to care full disconnect all the devices like USBs , Printers even LAN connections as well and the run the bios file it will automatically restart the systems.
But make sure that you download and install the proper bios file from the Motherboard manufactures web site that to with the proper version.
Because incorrect or partial bios updated could harm your motherboard.
Thanks and regards,
