Unlocking the Secrets of BIOS: How to Reset It on Your PC

When dealing with malfunctioning BIOS settings, resetting it can restore functionality to your PC. This guide explains why and how to reset your BIOS efficiently.

What is BIOS?

BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) is essential software that manages your computer’s hardware during the booting process. It checks hardware integrity and provides the necessary interface for the operating system to control these components effectively.

Why Should You Reset BIOS?

Resetting BIOS can be essential in various scenarios, such as undoing problematic changes, reverting to the original boot menu settings, switching from Legacy to UEFI mode, enabling Secure Boot, and even resolving password issues. Below are common reasons for a BIOS reset:

• Incorrect voltage settings or overclocking values.
• Incompatibility with new hardware components.
• Persistent display issues or boot loops.
• BIOS values not retaining changes.

Method 1: Power Button Reset

This simple method works on most modern PCs. If your system is experiencing boot loops due to misconfigured BIOS settings, holding down the power button for over 10 seconds can initiate an automatic reset. This process won’t reset your BIOS password, so ensure you use the right method if password recovery is needed.

Method 2: Reset from Within BIOS

If able to access BIOS, you can reset it using the ‘Load Setup Defaults’ option. This option’s name may vary depending on your motherboard manufacturer.

Option 1: Access BIOS from Windows

1. Step 1: Initiate Restart Sequence

   Press the Win key, select the ‘Power’ icon, hold down Shift, and click ‘Restart’.

2. Step 2: Navigate to Troubleshoot

   On the blue options screen, click ‘Troubleshoot’.

3. Step 3: Select Advanced Options

   Proceed to ‘Advanced options’.

4. Step 4: Choose UEFI Firmware Settings

   Select ‘UEFI Firmware Settings’ and click ‘Restart’.

5. Step 5: Load Default Settings

   Once in BIOS, navigate to ‘Load Setup Defaults’ and confirm the selection.

Option 2: Access BIOS from Boot Splash Screen

Restarting your PC and pressing the appropriate key at the boot screen can take you directly into the BIOS. Different manufacturers require different keys:

• Acer: Del or F2
• Dell: F2 or F12

Once inside, locate the ‘Load Setup Defaults’ option to reset BIOS settings.

Method 3: Reset via CMOS

You can reset BIOS firmware via CMOS by either disconnecting the battery or using the jumper method.

Option 1: Clear CMOS by Disconnecting the Battery

To clear CMOS, disconnect the battery located on the motherboard for 8-10 minutes to reset the BIOS settings back to default.

Option 2: Clear CMOS with a Jumper

Look for a CLEAR CMOS jumper on your motherboard. By shorting this jumper, you can reset the BIOS settings effectively.

Can You Reset the BIOS Password?

Resetting the BIOS password is possible if you remember it. However, forget your password? Resetting BIOS via the methods above will remove all passwords.

Clearing CMOS Did Not Reset BIOS, What to Do?

If CMOS clearing fails to reset the BIOS, consider these options:

Check for Specific Button

Some motherboards feature a dedicated reset button. Consult your manufacturer’s manual for guidance.

Discharge Every Capacitor

Ensure capacitors are discharged by unplugging your system and holding the power button for a few seconds.

Use a Different Tool to Short Your Pins

If you’re using a tool to short pins, switch to another tool, as included materials or coatings may affect functionality.

Contact Your Manufacturer

If all else fails, contact the manufacturer for specific advice regarding your system’s BIOS.

Cleared CMOS but Facing Issues? Try These Fixes!

If you experience issues post-CMOS reset, here’s how to troubleshoot:

If Windows Won’t Boot

Access BIOS to check and adjust boot order and priorities if Windows fails to boot.

If Display Won’t Show Anything

Try connecting to an external display. If that works, you may need to reflash BIOS.

If Different Postcode Errors Show Up Each Time

Random postcode errors could indicate hardware damage. Reseat your battery and retry the BIOS clearing methods.

Conclusion

Resetting the BIOS can resolve various issues related to hardware and booting. With these methods, you can restore settings to factory defaults and regain control over your system. If any point is unclear, feel free to reach out for assistance!
