The BIOS, or basic input/output system, of a computer controls the most fundamental commands that enable your computer to boot into an operating system. It is housed on a little chip on the motherboard.

The maker of your PC might occasionally provide BIOS updates with particular upgrades. But generally speaking, you shouldn’t have to change it very frequently, if at all. You probably won’t notice a significant gain because BIOS updates rarely bring new features or significant speed increases. You’re better off leaving the most recent BIOS alone unless it includes security updates, support for brand-new hardware you intend to utilize, or resolves a bug that has been affecting your regular usage.

But here’s how to update your BIOS if you belong to one of those groups and need to.

BEFORE WE BEGIN, A CAUTION Be aware that using this interface can differ slightly from computer to computer, particularly if you have a more recent device running a Unified Extensible Firmware Interface, or UEFI (which, despite being more capable than its older sibling, is still often referred to as BIOS). The following instructions should nevertheless put you in the right general direction even though we are unable to tell you exactly what to click on.

Installing (or “flashing”) a new BIOS is riskier than updating a straightforward Windows software because if something goes wrong, you risk permanently damaging your machine. Although changing your BIOS has never been a problem for me, and I’ve done it numerous times, it’s still vital to exercise caution.

DONATE FOR THE UPDATE

You’ll need to format a flash drive, copy the new BIOS file to it, and restart your computer while hitting a key to access the BIOS setup (often Delete, F2, or another key you’ll see on-screen at startup). This is necessary for many PCs, especially older ones.

Make a note of any settings you’ve modified in the past while you’re within the BIOS because an update will typically reset your system to its default settings. Taking pictures can help you recall your setup if you need to!

Then, find the option to upgrade your firmware, and you may use the file on your flash drive to launch the update tool. Avoid interrupting the procedure or turning off your computer at this time at all costs to avoid making your computer inoperable.
