Navigating the Maze of Hardware Upgrades: When USB and Ethernet Fail


Could you provide your expert insight on an issue where a computer ceases to recognize Ethernet and USB connections after some time? This problem started occurring following a hardware upgrade, which included a new GPU (6700xt), CPU (5800X3D), PSU (750w), and the addition of an SSD with a fresh Windows installation on an M.2 drive. The disconnections happen sporadically; sometimes instantly, other times after a period of use. Notably, the issue persisted even when the system was booted in safe mode, triggered specifically while downloading a game via Steam. What could be the potential causes and solutions for this problem?


When a computer starts experiencing issues with Ethernet and USB connectivity, especially after a significant hardware upgrade, it can be both perplexing and frustrating. The symptoms described—intermittent loss of connection that occurs randomly or during specific activities like downloading a game—suggest a few potential culprits that are worth investigating.


Driver Conflicts or Outdated Drivers:

After installing new hardware, it’s crucial to ensure that all drivers are up to date and compatible with the new components. Outdated or incorrect drivers can lead to conflicts that cause peripherals to disconnect.


Power Supply Insufficiency:

Even though a 750W PSU has been installed, it’s essential to verify that it can handle the peak loads of all components, especially under high-stress activities like gaming or downloading large files.



High-performance components like the 6700xt GPU and 5800X3D CPU can generate significant heat. If the cooling system isn’t adequate, overheating can occur, leading to system instability and connectivity loss.


Faulty Hardware:

There’s always a possibility that one of the new components is defective. This could be the motherboard’s USB or Ethernet ports, the SSD, or even the new GPU or CPU.


Software Issues:

The fresh Windows installation might have gone awry, or there could be conflicts with certain applications, such as Steam, that manifest as connectivity problems.



Update Drivers:

Ensure all drivers, particularly chipset, USB, and Ethernet drivers, are up to date. Visit the manufacturer’s website for the latest versions.


Check Power Requirements:

Use a PSU calculator online to determine if your PSU can handle the load. If it falls short, consider upgrading to a higher wattage unit.


Monitor Temperatures:

Use software to monitor the temperatures of your CPU and GPU. If they’re running hot, improve cooling with better fans or a more efficient cooling system.


Test Components:

If possible, test each new component individually in a different system to rule out hardware defects.


Reinstall Windows:

If all else fails, a clean reinstallation of Windows might resolve any underlying software issues.


Consult with a Professional:

If you’re unable to diagnose the issue yourself, it might be time to consult with a professional technician who can run more advanced diagnostics.

In conclusion, while the problem is certainly a nuisance, the good news is that it’s likely solvable with some troubleshooting. By methodically working through each potential cause, you can identify the root of the issue and take the appropriate steps to resolve it, restoring your system’s stability and connectivity. Remember, when dealing with complex systems, patience and a systematic approach are your best allies.
