Step-by-Step Guide: How to Clear CMOS on Your Gigabyte Aorus Motherboard

Clearing the CMOS (Complementary Metal-Oxide-Semiconductor) on a Gigabyte AORUS motherboard is a crucial step in troubleshooting system issues, updating BIOS, or resetting overclocking settings. This comprehensive guide will provide you with step-by-step instructions and troubleshooting tips to ensure a successful CMOS clear.

Identifying the CMOS Jumper

Locate the CMOS jumper on your Gigabyte AORUS motherboard. It is typically a two-pin or three-pin jumper labeled “CLR_CMOS” or “CLRTC.” The jumper is usually located near the battery or the bottom right corner of the motherboard.

Clearing CMOS Using Jumper Method

1. Power down the system: Turn off the computer and unplug it from the power outlet.
2. Locate the CMOS jumper: Refer to the motherboard manual or the section above to identify the CMOS jumper.
3. Remove the jumper: Use a pair of tweezers or a small screwdriver to gently lift the jumper off the pins.
4. Wait for 10-15 seconds: This allows the CMOS to discharge and reset.
5. Replace the jumper: Carefully place the jumper back onto the pins in the original position.
6. Power on the system: Plug in the computer and turn it on.

Clearing CMOS Using Battery Removal Method

1. Power down the system: Turn off the computer and unplug it from the power outlet.
2. Remove the side panel: Open the computer case and remove the side panel to access the motherboard.
3. Locate the CMOS battery: Find the small, round battery on the motherboard. It is usually located near the bottom right corner.
4. Remove the battery: Gently pry the battery out of its socket using a plastic tool or your fingers.
5. Wait for 10-15 seconds: This allows the CMOS to discharge and reset.
6. Replace the battery: Insert a new or fully charged battery into the socket.
7. Power on the system: Plug in the computer and turn it on.

Troubleshooting Tips

• No display after clearing CMOS: Ensure that all cables are securely connected and that the monitor is turned on. If the issue persists, try replacing the CMOS battery or resetting the BIOS using the “Reset to Default” option in the BIOS menu.
• Error messages during boot: If you encounter error messages after clearing CMOS, it may indicate a hardware issue. Check the motherboard for any loose components or damage.
• CMOS settings not reset: If the CMOS settings are not reset after following the steps above, it could be due to a faulty CMOS battery. Replace the battery with a new one.

Additional Tips

• Use a non-conductive tool: When handling the CMOS jumper or battery, use a non-conductive tool to avoid damaging the motherboard.
• Clear CMOS before updating BIOS: It is recommended to clear the CMOS before updating the BIOS to ensure that the new BIOS settings are applied correctly.
• Reset BIOS settings manually: If you prefer not to clear the CMOS, you can reset the BIOS settings manually by entering the BIOS menu and selecting the “Reset to Default” option.

When to Clear CMOS

• When troubleshooting system issues that cannot be resolved by other means
• Before updating the BIOS
• After overclocking the system and experiencing instability
• After replacing the motherboard or CPU
• To reset forgotten BIOS passwords

Common Questions and Answers

Q: Can I clear the CMOS without removing the battery or jumper?
A: Yes, some Gigabyte AORUS motherboards have a dedicated “Clear CMOS” button or switch. Consult your motherboard manual for specific instructions.

Q: How often should I clear the CMOS?
A: Clearing the CMOS is not a regular maintenance task. It should only be done when necessary, such as when troubleshooting system issues or updating the BIOS.

Q: Can I damage my motherboard by clearing the CMOS?
A: No, clearing the CMOS does not damage the motherboard. However, improper handling of the CMOS jumper or battery can cause damage.
