How to update BIOS



Sorry my board is actually the ga-b250m-ds3h the gigabyte one. Can I find that on gigabytes website?
 

Lol.. that's why it is important to give the full name of the board, I guess. This should be your board. If so, there may be a flash option in your BIOS itself to do that*. If not, Gigabyte offers the @BIOS Windows app to do that. You can find it on this page.

* A quick check of the manual didn't show that option. So, you'll have to use @BIOS.
