How to Check BIOS Version: A Step-by-Step Guide


When it comes to troubleshooting computer issues or ensuring compatibility with certain software, knowing your BIOS version can be incredibly helpful. BIOS (Basic Input Output System) is the firmware that runs on your computer’s motherboard and initializes hardware components before the operating system starts.

In this comprehensive guide, we will walk you through the step-by-step process of checking your BIOS version. Whether you’re an experienced computer user or a novice, this guide will provide you with all the information you need.

Step 1: Accessing the BIOS

To check your BIOS version, you need to access the BIOS settings on your computer. Start by restarting your computer and continuously pressing the designated key (usually Del, F2, or F10) during the boot process. This will bring you to the BIOS menu.

Step 2: Finding the BIOS Version

Once you’re in the BIOS menu, navigate to the “System Information” or a similar tab using the arrow keys on your keyboard. Look for an entry called “BIOS” or “Firmware Version.” Here, you will find the information you’re looking for.

Step 3: Recording the BIOS Version

Now that you’ve found the BIOS version, it’s essential to record it for future reference. Write down the version number, date, and any other relevant information associated with your BIOS.

Why Should You Check Your BIOS Version?

Checking your BIOS version is crucial for several reasons. First, it allows you to determine if your system is up-to-date with the latest firmware. Manufacturers often release BIOS updates to improve compatibility, fix bugs, and enhance system performance. By knowing your BIOS version, you can decide if an update is necessary.

Furthermore, certain software and hardware may require specific BIOS versions for optimal performance. Whether you’re installing a new graphics card or upgrading your operating system, knowing your BIOS version will ensure compatibility.

Common BIOS Error Messages

Sometimes, you may encounter error messages related to your BIOS version. Here are a few common ones and their possible solutions:

1. “BIOS not found” – This error usually occurs when there is a problem with the BIOS itself or the motherboard. Check the physical connections and, if the issue persists, consider seeking professional help.

2. “CMOS checksum error” – This message indicates that the BIOS settings have been corrupted or changed. Resetting the BIOS to its default settings should resolve this issue.

3. “BIOS update failed” – If you encounter this error, make sure you’re using the correct BIOS update for your motherboard model. Double-check the file integrity and consider consulting the manufacturer’s support for assistance.

Troubleshooting BIOS Update Issues

Updating your BIOS can sometimes be a complicated process. Here are a few troubleshooting tips if you encounter issues during the update:

1. Ensure a stable power source – A sudden power outage or interruption during the update can lead to a corrupt BIOS. Make sure your computer is connected to a reliable power source throughout the update process.

2. Use a USB flash drive – If your computer supports it, using a USB flash drive to update the BIOS is often more reliable than using other methods. Follow the manufacturer’s instructions carefully and ensure you’re using a formatted and compatible USB drive.

3. Consult the manufacturer’s documentation – If you’re uncertain about the update process or encounter specific error messages, refer to the manufacturer’s documentation or support resources. They will provide detailed instructions and solutions tailored to your motherboard model.


Checking your BIOS version is a straightforward process that can provide valuable information and help troubleshoot compatibility issues. By following the step-by-step guide outlined above, you can confidently navigate your computer’s BIOS menu and find the necessary version information. Remember, keeping your BIOS up-to-date is essential for optimal system performance and compatibility with the latest software and hardware.
