The Hyper-Transport-Sync-Flood error on Windows 11 can be frustrating and may cause your system to slow down or become unresponsive. This error usually occurs due to issues with hardware communication or driver conflicts. Fortunately, there are several easy ways to fix this problem.

In this guide, we will walk you through simple, step-by-step solutions to resolve the Hyper-Transport-Sync-Flood error. No advanced technical skills are required, and we will explain everything clearly.

By following these instructions, you can ensure your Windows 11 system runs smoothly again without interruptions from this error. Let’s get started with some basic checks before diving into troubleshooting.

Understanding the cause of this error helps in fixing it properly, so each step includes explanations for why it’s important.

Quick Note: Prerequisites and Initial Checks

Before starting the troubleshooting process, make sure to check these basic things:

Restart Your Computer: Sometimes, a simple reboot can clear temporary glitches causing the error.
Check for Windows Updates: Ensure your system is up to date, as Microsoft often releases fixes for known issues.
Disconnect External Devices: Unplug any unnecessary USB devices or external hardware to rule out hardware conflicts.
Backup Important Data: It’s always a good idea to back up your files before making system changes.

Step 1: Update Your Device Drivers

Outdated or corrupted device drivers often cause communication errors like the Hyper-Transport-Sync-Flood. Updating your drivers can fix this.

Press Win + X and select Device Manager.
Expand categories such as Network adapters or System devices to find your hardware devices.
Right-click on your device and choose Update driver.
Select Search automatically for drivers to let Windows find the latest drivers.
Repeat this for all major devices related to your motherboard and network.

Updating drivers ensures your hardware communicates correctly with Windows, preventing sync errors.

Step 2: Run Windows Troubleshooter for Hardware and Devices

Windows includes built-in troubleshooters that can detect and fix common hardware problems automatically.

Press Win + I to open Settings.
Go to System > Troubleshoot > Other troubleshooters.
Find Hardware and Devices and click Run.
Follow the on-screen instructions to complete the troubleshooting process.

This step can detect misconfigured settings or minor hardware issues causing the error.

Step 3: Check for Malware and Viruses

Malware can interfere with system processes and cause errors. Running a full system scan helps rule this out.

Open Windows Security by typing it in the Start menu.
Click on Virus & threat protection.
Choose Quick scan or Full scan for a more thorough check.
Follow any recommendations if threats are found.

Keeping your system malware-free ensures smooth operation and reduces unexpected errors.

Step 4: Reset Network Settings

Since the Hyper-Transport protocol relates to system communication, resetting your network settings can help fix sync issues.

Go to Settings > Network & Internet > Advanced network settings.
Click on Network reset at the bottom of the page.
Confirm by clicking Reset now.
Your PC will restart, and network settings will return to default.

This step resolves possible network misconfigurations affecting Hyper-Transport synchronization.

Step 5: Update Your BIOS/UEFI Firmware

Sometimes, outdated BIOS or UEFI firmware on your motherboard can cause hardware communication errors.

Identify your motherboard model by opening System Information (search msinfo32 in Start menu).
Visit the motherboard manufacturer’s official website.
Download the latest BIOS/UEFI firmware update available for your model.
Follow the manufacturer’s instructions carefully to update the firmware.

Updating BIOS improves hardware compatibility and can fix low-level communication issues.

Alternative Methods and Advanced Options

If the above steps don’t work, you can try these advanced options:

Perform a Clean Boot: This starts Windows with minimal drivers and startup programs to identify if third-party software causes conflicts.
Run System File Checker (SFC): Open Command Prompt as administrator and run sfc /scannow to repair corrupted system files.
Use DISM Tool: Run DISM /Online /Cleanup-Image /RestoreHealth in Command Prompt to fix Windows image corruption.
