Updating bios benefit components of working memory updating
Like most things in the technology world, your motherboard software (BIOS) occasionally gets updated, sometimes to fix bugs and other times to add new features.
As part of some hardware troubleshooting processes, especially those that involve new RAM or a new CPU that won't work correctly, updating BIOS to the latest version is a good thing to try.
In other words, if the BIOS update program supplied only works from within Windows, you'll have to stick to Method 1.
A much easier way to check the BIOS version running on your computer's motherboard is via a program called Microsoft System Information.
