Installing a new GPU in your system is often an exciting upgrade, promising better graphics performance for gaming or productivity tasks. However, it can sometimes lead to unexpected issues, like the Ethernet problem on the Gigabyte B650 AORUS motherboard after installing a GPU. If you’ve encountered this issue, don’t worry. This article will guide you through understanding and fixing the problem.

Why Does the Ethernet Issue Happen?

When you install a new GPU, especially a high-power one, several things can go wrong with the other components in your system. Here’s why the Gigabyte B650 AORUS Ethernet problem after installing a GPU might occur:

  1. Power Supply Issues: Your GPU might be drawing more power than your power supply can handle, leading to insufficient power for other components like the Ethernet controller.
  2. PCIe Lane Sharing: Installing a GPU can sometimes cause conflicts on the motherboard’s PCIe lanes, which can interfere with the onboard Ethernet controller.
  3. Driver Conflicts: The new GPU installation might lead to driver conflicts or incorrect driver installations that impact the Ethernet functionality.
  4. BIOS Settings: A new GPU might change certain BIOS settings, particularly if it’s a more advanced model, which could disable or affect the Ethernet port.
  5. Physical Obstruction or Installation Errors: The GPU could physically obstruct other components or cause accidental disconnections during installation.

Steps to Troubleshoot and Fix the Ethernet Problem

Here’s a step-by-step guide to resolve the Ethernet problem on your Gigabyte B650 AORUS after installing a GPU.

1. Check Power Supply Capacity

First, verify that your power supply unit (PSU) has enough wattage to support both your new GPU and all other components. High-end GPUs can require significant power, and if your PSU is underpowered, it might prioritize the GPU, leading to issues with other components.

  • Solution: If your PSU is not adequate, consider upgrading to a higher wattage unit. A PSU calculator can help you determine the required wattage for your system.

2. Inspect PCIe Lane Allocation

Some motherboards, including the Gigabyte B650 AORUS, share PCIe lanes between components. When a new GPU is installed, it might affect how lanes are allocated, potentially disabling or reducing the functionality of other components like the Ethernet controller.

  • Solution: Consult your motherboard’s manual to check how PCIe lanes are distributed and whether your GPU is causing any conflicts. Adjusting the GPU to a different slot or changing BIOS settings may help.

3. Update or Reinstall Drivers

New GPU installations can sometimes cause driver conflicts. The Ethernet controller may be affected by changes in how the system handles hardware after the GPU is installed.

  • Solution: Go to the Gigabyte website and download the latest Ethernet drivers for your B650 AORUS motherboard. Also, update your GPU drivers from the manufacturer’s website. If necessary, uninstall and reinstall both drivers.

4. Check BIOS Settings

A new GPU might automatically change some settings in your BIOS, especially if the GPU has features like onboard network controllers.

  • Solution: Enter the BIOS setup by pressing the designated key (usually Del or F2) during boot. Check the settings for onboard devices and ensure that the Ethernet controller is enabled. You might also want to reset the BIOS to default settings to see if it resolves the issue.

5. Physical Inspection

Finally, make sure that the GPU installation did not cause any physical problems, such as dislodging cables or obstructing airflow that could affect the Ethernet port or its related circuitry.

  • Solution: Open your case and carefully inspect the installation. Ensure that all cables are securely connected and that the GPU is properly seated. Additionally, check that the GPU isn’t blocking any other components on the motherboard.

Additional Troubleshooting Tips

  • Use an External Ethernet Adapter: As a temporary fix, you can use a USB Ethernet adapter if you need to restore internet access while troubleshooting the onboard Ethernet issue.
  • Check for OS-related Issues: Sometimes, the operating system might misconfigure the Ethernet adapter after a hardware change. Check your network settings in your operating system and try resetting the network configuration.
  • Consult Support Forums: If the problem persists, consider reaching out to Gigabyte’s support or checking community forums where other users might have faced and resolved similar issues.

Conclusion

The Gigabyte B650 AORUS Ethernet problem after installing a GPU can be frustrating, but with the right steps, it’s often fixable. Start by checking your power supply, PCIe lane configuration, and drivers. If those don’t work, dive into the BIOS settings and inspect the physical installation of your components. With careful troubleshooting, you should be able to resolve the issue and enjoy your new GPU without compromising your network connectivity.
