How to update your BIOS without a CPU

Sometimes it can be difficult to get your computer going if you don’t have the original package, such as in a Build-A-Board situation. You may need to update the BIOS, though! –

Won’t the computer turn on? Don’t worry; just update your BIOS under a USB flash drive!

A quick lookup of “BIOS” in this article will tell you all about how to flash new versions and what kind can help with any problems saving logos or passwords.

Your System might turn on, but you’ll have a hard time seeing anything because the motherboard doesn’t know how to communicate with your computer’s processor.

BIOS (or Basic Input/Output System) is the foundation of your computer’s hardware and software. It determines what operations can be performed on a particular machine, such as showing you how much memory exists or loading an operating system for the startup, including the power supply.

Among many other things that depend upon it! The term typically refers to the ATX motherboard released before 2006, but some older boards require updating their specific firmware, too, which we will get into later below…

If you’re having trouble with any of the following, it might be time for a BIOS update:

  • Having difficulty POST-ing (power-on self-test)
  • Overheating
  • Random crashes or hangs
  • Incorrect CPU fan speeds are being reported
  • The System fails to enter sleep mode properly. Also, check the power connectors; the BIOS without CPU3.

These are only a few examples, so check your motherboard’s manufacturer’s website for an updated list of BIOS changes made by the CPU cable.

What Is BIOS Flashback?

Some newer boards have a nifty feature called BIOS flashback. This allows you to update the BIOS without a CPU or memory installed.

You’ll need the latest firmware file from the manufacturer, which will come in the form of a .cap file. Copy this to a USB drive and insert it into the designated USB port and BIOS flash button, the BIOS flashback feature embedded under the BIOS menu.

Once you’ve done this, press the flashback button (usually labeled with a lightning icon) and wait for the process to complete.

Doing this is the last resort if you can’t seem to get your System POST-ing after repeated attempts. If this doesn’t work, you’ll need to RMA the board of Ryzen 5000.

  • ASRock motherboards: BIOS Flashback Button
  • Asus motherboards: USB BIOS Flashback
  • Gigabyte motherboards: Q-Flash Plus (not to be confused with Q-Flash)
  • MSI motherboards: Flash BIOS Button (not to be confused with M-Flash)

BIOS Flashback is a great way to update your computer’s BIOS without installing any hardware. It requires an internet connection and the right motherboard, which you can buy from many retailers such as Amazon or eBay!

How to Update Your BIOS

Updating your BIOS has come a long way since the early days of personal computing. Back then, you needed a DOS-based bootable floppy disk and knowledge of some basic commands to get it done.

Nowadays, most manufacturers include a Windows-based program that handles the whole process for you. The program will prompt you for the new BIOS file, ask you to confirm that you want to update the BIOS, and then do its thing, the exact motherboard model. Once done, you’ll need to restart your computer for the changes.

Determining if you need a BIOS Update

Checking if you have the latest BIOS is easy. Restart your computer and as it’s booting up, pay close attention to the screen of the motherboard BIOS. 

Near the POST stage, it should tell you your BIOS version.

You can check this information in Windows by going to the System Properties page (right-click on My Computer and select Properties). On the System Properties page, look for the BIOS version under the System section, following the BIOS update process.

If you see that your BIOS version is out of date, go to the manufacturer’s website and download the latest version. Select the correct BIOS for your motherboard model and version containing the special USB port with LED lights.

Updating Your BIOS

Once you have downloaded the new BIOS, you must put it on a bootable floppy disk or USB drive. The process for doing this varies from manufacturer to manufacturer, so be sure to read the instructions carefully current community.

Once you have created the bootable media, boot from it and follow the on-screen instructions to update your BIOS graphics card, including the special features from the largest file.

In most cases, the process is pretty straightforward, and you shouldn’t encounter any problems. But if something does go wrong, don’t panic! There’s usually a way to recover from a failed BIOS update.

What Type of USB Drive Should I Use for BIOS Flashback?

Any USB drive will work as long as it’s formatted as FAT32. If you’re unsure how to do this, just use a Windows-based utility like HP USB Disk Storage Format Tool to format the drive.

Once you’ve done this, copy the BIOS file to the root directory of the USB drive. Then, plug the USB drive into the designated port on your motherboard and press the BIOS flashback button. The process will take a few minutes to complete, after which you can boot into your BIOS and check that the update was successful.

Contact the manufacturer’s customer support team for assistance if you run into any problems. They should be able to help you recover from a failed BIOS update and get your System up and running again.

Recovering from a Failed BIOS Update

If your computer doesn’t boot after you update the BIOS, don’t panic! There’s usually a way to recover from a failed BIOS update.

The first thing you need to do is see if you can boot into Safe Mode. To do this, just restart your computer and press the F8 key as it’s booting up. This will bring up the Advanced Boot Options menu. From here, select Safe Mode and see if your computer will boot into Windows.

If you can boot into Safe Mode, you can try using the System Restore feature most motherboards that will support any type of USB drive, but it’s always best to check the manufacturer’s website before proceeding. 

Asus recommends using a USB 2.0 drive with at least 8GB of storage space. The drive doesn’t need to be bootable and can be formatted as FAT32 or N.
