Note that the PC manufacturer remedies some of these problems for you.For example, a BIOS update from Dell will be packaged into an executable file that will not only check to make sure the version of the BIOS you are installing is compatible with your system, but will also go ahead flash the BIOS without you having to manually do it.Unlike the operating system, the BIOS is low-level software that is stored on a chip on the motherboard of the computer.In order to update this low-level software, you normally have to “flash the BIOS“, which will replace the old software with the new version.Now that I’ve explained the reasons for and against updating your BIOS, let’s talk about how to figure out whether there is an update for your BIOS.The first thing you’ll need to do is check the current version of your BIOS, which I have already explained previously in the linked article.
Just because there is an update for your BIOS does not mean that you should necessarily install it.It’s a myth that BIOS updates somehow make your computer faster or run better.In some rare instances, a BIOS update can fix a motherboard issue that might make your computer perform better, but it’s usually not related to speed.Here's everything you need to know about how to update a PC BIOS, whether traditional or the newer UEFI standard.Before you start, a warning: if something goes wrong during the BIOS update, your computer could be rendered useless.If there's a power cut, or the computer gets turned off while updating, it could mean that it's unable to boot at all. For this reason, it's worth checking whether you really need to update your BIOS.Read the release notes of the latest version (and each version back to the one currently installed) to see whether it will add the features you need or fix a problem you're having.As you can see, this update fixes some USB keyboard/mouse issue and upgrades e PSA to the latest version. Well, if you don’t have any keyboard or mouse issue and no other problem with your system, it’s probably not necessary.For custom built PCs, you will need to visit the motherboard manufacturer website and download the drivers from there. It also gives you a description of what the update includes.Of course, you may need to Google some of the technical terms in order to understand what they are talking about.Check the version and date of the BIOS listed on the website and compare it to the one on your system.
