Different motherboards have different quirks when it comes to using the BIOS Flash button, too.įor example, the standard information is that you should use the BIOS Flash button without any other hardware installed on the motherboard (that means no GPU, no RAM, no SSDs or HDDs connected). Frustratingly, it might not be apparent that the BIOS flash has failed until you attempt to install your new CPU or enter the BIOS. The BIOS Flash button isn't always guaranteed to work. If the BIOS flash process extends beyond 15 to 20 minutes, it's a safe bet that it isn't working and that you should try again. When the process completes, the motherboard will restart, or it may shut down depending on the manufacturer. Most motherboards with a BIOS Flash button also have a progress indicator of some sort, be that a blinking LED or a visual display on the motherboard. The BIOS flash process can take up to 10 minutes, and sometimes more, depending on the size of the new BIOS installation. Now, with the power supply switched on, press the BIOS Flash button.After connecting the power supply, you can insert the USB drive into the manufacturer-specified BIOS Flash USB port on the motherboard.

Before inserting the USB BIOS drive, you need to connect the 24-pin and 8-pin power connectors to your motherboard (otherwise, it won't switch on).That means just the BIOS file, not within another folder, copied directly into the USB drive. Once the drive format completes, you can copy the renamed BIOS file to the root of the USB drive.Make sure Quick Format is checked, then hit Start. Insert the drive into your computer, then right-click and select Format. The drive must also use the FAT32 file system.Low capacity is typically 32GB or smaller, and it must be a USB 2.0 drive unless stated otherwise. Now, you need a small capacity USB 2.0 drive.The manufacturer instructions will tell you exactly what to name the file. Once the download completes, extract the files from the archive.

If you're upgrading to support a new CPU, make sure you read the description properly to ensure the BIOS you choose delivers that support.

Head to the manufacturer's website and download the correct BIOS file for your motherboard.
