If you want to upgrade your computer’s CPU to a new CPU-possibly one that wasn’t yet released when you purchased your motherboard-you may need to update the BIOS.īe sure to check the changelog for the BIOS updates and see if they actually have an update you require.

Hardware Support: Some motherboard manufacturers add support for new CPUs, and potentially other hardware, in BIOS updates.

A manufacturer may even advise you to update your BIOS if you contact tech support and have a problem that has been fixed with an update.

Bugs: If you are experiencing bugs that are fixed in a newer version of the BIOS for your computer (check the BIOS changelog on the manufacturer’s website), you may be able to fix them by updating your BIOS.

Here are a few cases where updating makes sense: Given that you probably will not see any improvements from updating your BIOS, that new bugs could pop up, and the potential for errors while flashing, you shouldn’t update your BIOS unless you have a reason to. Computers should ideally have a backup BIOS stored in read-only memory, but not all computers do. If your computer loses power while flashing the BIOS, your computer could become “ bricked” and unable to boot. Each manufacturer has its own instructions for flashing a BIOS. You will often want to flash your computer from DOS (yes, DOS-you may have to create a bootable USB drive with DOS on it and restart into that environment), as problems could occur when flashing from Windows.

In some cases, you may even experience new bugs with a new version of the BIOS, as the BIOS that came with your computer may have gone through more testing.įlashing a BIOS isn’t as easy as installing a normal software update. You likely won’t see the difference between the new BIOS version and the old one.

If your computer is working properly, you probably shouldn’t update your BIOS.

BIOS updates typically have very short change logs-they may fix a bug with an obscure piece of hardware or add support for a new model of CPU. Why You Probably Shouldn’t Update Your BIOSīIOS updates aren’t big software upgrades that add new features, security patches, or performance improvements. BIOSes are computer-specific (or motherboard-specific), so you will need the BIOS for your exact model of computer (or motherboard) to update your computer’s BIOS.
