Resetting your BIOS can be a crucial step in troubleshooting various system issues, optimizing performance, or preparing your PC for new hardware. While many users might only focus on their operating system, understanding how to reset the BIOS on Windows 11 is equally important for ensuring your PC runs smoothly. This article is a comprehensive guide to help you navigate the process of resetting your BIOS, explaining its significance and providing step-by-step instructions.
Understanding BIOS
BIOS stands for Basic Input/Output System. It is the firmware that initializes and tests hardware components when you power on your computer. The BIOS also provides a runtime environment for the operating system and other programs. It resides on a chip on the motherboard and is crucial for booting the operating system.
In modern computers, traditional BIOS has mostly been replaced by UEFI (Unified Extensible Firmware Interface). UEFI offers more advanced features like faster boot times, support for larger hard drives, and a graphical user interface.
Why Reset the BIOS?
There are several reasons you may want to reset your BIOS:
Troubleshooting Issues
: If your computer is not booting properly, resetting the BIOS can help rectify settings that might be causing the problem.
Overclocking Problems
: If you’ve overclocked your CPU or RAM and are experiencing instability, resetting the BIOS will return the settings to their default values.
New Hardware Installation
: When installing new hardware, especially RAID configurations or graphics cards, resetting the BIOS can help the system recognize the new components.
Security Concerns
: If you’ve forgotten your BIOS password or if you believe that your settings have been tampered with, a reset may be necessary.
Performance Enhancements
: Sometimes, resetting can help optimize system performance if settings have been misconfigured over time.
Precautions Before Resetting BIOS
Before proceeding with the reset, it’s essential to consider a few precautions:
Backup Important Data
: While resetting the BIOS doesn’t directly affect your files, it’s always wise to have your important data backed up.
Document Current Settings
: If your BIOS is configured for optimal performance or for specific tasks, take note of those settings. This will help you restore them later if required.
Understand the Risks
: Incorrect BIOS settings can lead to failure to boot. Be cautious and informed about the changes you are making.
How to Access BIOS
Before you can reset the BIOS, you need to access it. The method to enter the BIOS setup can vary by manufacturer, but the general approach is as follows:
Restart Your Computer
: Click on the Start menu, then select ‘Restart’.
Press the BIOS Key Prompt
: As your computer starts up, look for a boot menu prompt on the screen. Common keys include F2, Del, Esc, F10, and F12. Press the appropriate key repeatedly right after turning on your machine but before Windows begins to load.
Use Advanced Startup Options

Resetting BIOS via CMOS Battery Removal
If you’re unable to access BIOS or want to ensure a thorough reset, you can clear the BIOS settings by removing the CMOS battery. This method is often used when other reset methods fail.
Steps to Remove CMOS Battery
Turn Off Your Computer
: Completely shut down your machine and unplug it from the power source.
Open the Computer Case
: Depending on your system, you might need a screwdriver to remove the side panel.
Locate the CMOS Battery
: It’s a small, round battery (similar to a coin) typically located on the motherboard. Take note of how it is positioned before removal.
Remove the Battery
: Carefully pop it out. Wait for about 5 to 10 minutes to ensure all settings have cleared.
Reinsert the Battery
: Place the battery back in the same position, ensuring it’s seated properly.
Resassemble Your Case
: Close the case and reconnect all cables.
Power On the Computer
: Start your PC. Upon booting, the BIOS settings will be reset to factory defaults.
What to Expect After Resetting BIOS
After resetting your BIOS, several changes might occur:
Default Settings
: All settings, including boot priorities, drive configurations, and performance settings, will revert to their default values.
Time and Date Reset
: You’ll likely need to set the date and time again as this resets with the BIOS.
Drivers & Components
: In some cases, components such as RAID configurations may need to be reconfigured as well.
Secure Boot & TPM Settings
: If your machine has these features enabled, you may need to set them again.
Performance Settings
: You might notice an initial drop in performance if you had optimized settings for overclocking or power management, and you will need to make adjustments accordingly.
Final Steps After Resetting BIOS
Once your system boots up after resetting the BIOS, take the following actions:
Enter BIOS to Configure Settings
: If you had previously customized your BIOS settings, now is the time to re-enter and make adjustments as needed.
Check Hardware Configuration
: Ensure all new hardware is recognized by the BIOS.
Verify Boot Order
: Make sure your primary boot device is set correctly, especially if you have multiple drives or operating systems installed.
Monitor System Stability
: Pay attention to how your computer behaves. If problems persist, further investigation into hardware issues may be needed.
