Question:

Here are the system specifications and troubleshooting steps I’ve already attempted:

• Motherboard: Gigabyte B650M Pro AX rev. 1.2
• CPU: Ryzen 7800X3D
• RAM: XPG Lancer 2x16GB 6400MHz
• GPU: RTX 3080 Ti (also tested with GTX 1080)
• SSD: WD Blue 500GB
• HDD: WD Black 4TB

Troubleshooting steps taken:

• Updated BIOS to all available versions
• Tried various audio drivers
• Performed a BIOS reset
• Adjusted for a slow slew rate
• Turned off RGB lighting
• Used the front panel 3.5mm jack
• Assembled the build outside of the case”

This

version is structured to directly address an expert, outlining both the problem and the steps already taken to resolve it.

Answer:

A user has reported a disturbing noise emanating from their headphones and motherboard when starting Windows, which escalates with GPU load. This issue persists despite the GPU functioning normally on another system.

Expert Analysis:

The symptoms described suggest a possible electromagnetic interference (EMI) or a grounding issue, which can be exacerbated by high GPU loads due to increased power draw and electrical activity. The coil whine from the motherboard is a common phenomenon where electrical components emit a high-pitched sound under certain conditions, but it should not be audible through headphones.

Recommended Solutions:

1.

Power Supply Unit (PSU) Check:

Ensure the PSU is of high quality and has sufficient wattage to handle the system’s power requirements, especially under load.

2.

Grounding:

Verify that all components are properly grounded. A lack of proper grounding can lead to EMI, which may cause the noises heard.

3.

Isolation:

Try isolating the audio circuit from potential interference by using an external Digital-to-Analog Converter (DAC) or a sound card.

4.

Cable Management:

Re-examine cable routing to prevent any possible EMI from power cables affecting audio lines.

5.

Component Testing:

Test the motherboard with another CPU and RAM to rule out component-specific issues.

6.

Consult Manufacturer:

If the issue persists, reaching out to the motherboard manufacturer for support or considering an RMA might be necessary.

Conclusion:

The problem at hand is complex and may require a process of elimination to identify the root cause. The steps outlined above offer a comprehensive approach to diagnosing and potentially resolving the noise issue. It’s crucial to tackle such problems methodically, ensuring each component’s integrity and compatibility within the system.
