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.Flashing a BIOS isn’t as easy as installing a normal software update.

If you purchased a pre-built computer instead of building your own, head to the computer manufacturer’s website, look up the computer model, and look at its downloads page. Your BIOS download probably comes in an archive—usually a ZIP file. Inside, you’ll find some sort of BIOS file—in the screenshot below, it’s the E7887IMS.140 file.

The archive should also contain a README file that will walk you through updating to the new BIOS.

Updating your operating system and software is important.
