Power off when updating bios
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.
On the other hand, we have previously covered why you shouldn’t generally update your hardware drivers, although gamers will definitely want to update their graphics drivers. BIOS updates will not make your computer faster, they generally won’t add new features you need, and they may even cause additional problems.
You won’t get anything out of it except possible new problems.
You probably shouldn’t update your BIOS, but sometimes you need to.
If your computer is working properly, you probably shouldn’t update your BIOS.
You likely won’t see the difference between the new BIOS version and the old one.
You should only update your BIOS if the new version contains an improvement you need. When you power your computer on, your BIOS takes control, starting the power-on self test (POST) and passing control over to the boot loader, which boots your computer’s operating system.
