VIDEO_TDR_FAILURE

The VIDEO_TDR_FAILURE error (Technical Error: Time Detection and Recovery) indicates a problem with the display driver or the graphics hardware. It usually occurs when the GPU stops responding and Windows cannot reset it within the timeout limit.

Potential Causes and Diagnostic Steps

1. Driver Issues. Since you have already reinstalled the drivers, ensure you have the latest versions specifically from the manufacturer’s website.

2. Hardware Issues. Given the error code 43 in the Device Manager and the description of the issues encountered, it seems the GPU might be under duress following the recent hardware changes.

Steps to Diagnose and Potentially Salvage the GPU

1. Check Hardware Installation and Connections. Ensure all hardware components are correctly installed and seated.

2. Thermal Paste and Heatsink Installation. As noted by the technician, excessive thermal paste can lead to issues.

3. Consider re-evaluating the GPU and cooling system for any further damage.

Given the detailed steps you've already taken and the input from the service center, it seems plausible that the GPU might have sustained some level of damage or is experiencing instability due to temperature management issues. However, the hardware may still be salvageable, especially since you observed normal temperatures and stable performance for a while after reinserting the battery.

To definitively determine whether the GPU is salvageable and to resolve the VIDEO_TDR_FAILURE error, I recommend following the steps outlined above. If you continue to experience issues, it might be necessary to consult with a specialized repair technician or consider replacing the GPU or cooling system components.

I appreciate your patience and dedication to resolving this complex issue. Should you have any further questions or need additional assistance, please feel free to reach out.

Given that this seems to lean more towards a hardware issue, here are some more specific troubleshooting steps and considerations:

1. Re-check Cooling System and Thermal Management. Even though you have already addressed the thermal pads and paste, considering the intricate nature of these components, it’s essential to ensure they are optimal:

Microcracks in the Cooling System: Inspect with a magnifying glass or take it to a technician for a thorough examination to identify any microcracks or deformations in the cooling pipes.

Reapply Thermal Paste: Apply a high-quality thermal paste if reapplication is deemed necessary. The spread should be even and just enough to cover the surface without excess.

2. Evaluate GPU for Physical Damage. It’s crucial to examine the GPU and its surrounding components for any visible signs of damage.

Crystal Examination: Evaluating for punctures or damage to the GPU crystal might require professional diagnostic tools.

PCB Inspection: Ensure no dry solder joints or signs of damage on the PCB (Printed Circuit Board) of the GPU.

3. Driver Reinstallation Approach. Since forceful restarting during driver installation can exacerbate issues, use safe methods to reinstall drivers. Remove the existing drivers using Display Driver Uninstaller (DDU) in Safe Mode. Download the latest drivers from the manufacturer’s website (NVIDIA) for a clean install.

4. BIOS/UEFI Update: Visit the ASUS support website and download the latest BIOS update for your specific laptop model. Follow the instructions carefully to update the BIOS.

5. System Resource and Thermal Monitoring

Using monitoring software to keep an eye on system resources and temperatures during different states can provide insights. Use HWiNFO or MSI Afterburner to monitor GPU, CPU temperatures, and clock speeds. Check for unusual thermal spikes or drops that might indicate cooling inefficiency or GPU issues.

Given the symptoms, if the GPU indeed continues to fail under load even after attempting the aforementioned steps, it might be prudent to consider:

Professional Hardware Diagnostic: Engage with a professional service center equipped with the necessary tools to diagnose deeper GPU faults.

GPU Replacement: If the GPU or its cooling system is confirmed as the point of failure, look into feasible options for replacing these components.

You’ve done an excellent job troubleshooting so far, and I commend your thoroughness. By following these additional steps, we can aim to either pinpoint or rule out further potential causes of the VIDEO_TDR_FAILURE and hardware instability.

Thank you for your patience and dedication. Should you need any further assistance or specific guidance, please do not hesitate to reach out. Good luck, and I hope we can get your laptop back to optimal performance soon.
