Quick Note: Prerequisites and Preliminary Checks

  • Restart your computer: Sometimes, a simple reboot can clear temporary glitches causing the driver error.
  • Check for Windows updates: Make sure your system is fully updated, as Microsoft regularly releases fixes for driver-related issues.
  • Backup important data: Before making system changes, it’s good practice to back up your files to avoid data loss.
  • Note any recent changes: If you installed new hardware or software before the error appeared, this might be related.

Step 1: Update or Reinstall the NVHDA64V-SYS Driver

The NVHDA64V-SYS file is usually connected to audio or hardware drivers. An outdated or corrupted driver often causes errors. Updating or reinstalling the driver can fix these problems.

  1. Press Windows + X and select Device Manager.
  2. Look for categories like Sound, video and game controllers or System devices.
  3. Find the driver related to your audio device or the NVHDA64V-SYS file.
  4. Right-click the device and select Update driver.
  5. Choose Search automatically for updated driver software.
  6. Follow the on-screen instructions to complete the update.
  7. If updating does not help, right-click the device again and select Uninstall device.
  8. Restart your computer. Windows will attempt to reinstall the driver automatically.

Updating or reinstalling drivers ensures that your system uses the latest and most compatible software, reducing the chance of errors.

Step 2: Run the Windows Troubleshooter for Hardware and Devices

Windows 11 includes built-in troubleshooters designed to detect and fix common hardware problems automatically.

  1. Press Windows + I to open Settings.
  2. Go to System > Troubleshoot > Other troubleshooters.
  3. Scroll down to find Hardware and Devices and click Run.
  4. Follow the prompts to allow Windows to scan and fix any detected issues.

This tool is helpful as it can automatically identify driver conflicts or hardware-related problems without manual intervention.

Step 3: Check for System File Corruption Using SFC and DISM

Corrupt system files can cause driver errors like NVHDA64V-SYS. Windows provides tools to scan and repair these files.

  1. Press Windows + S, type cmd, right-click Command Prompt, and select Run as administrator.
  2. Type the following command and press Enter:
    sfc /scannow
  3. Wait for the scan to complete. It will automatically repair corrupted files if found.
  4. After that, type the following commands one by one, pressing Enter after each:
    DISM /Online /Cleanup-Image /CheckHealth
    DISM /Online /Cleanup-Image /ScanHealth
    DISM /Online /Cleanup-Image /RestoreHealth
  5. Restart your computer once all commands finish successfully.

Running these commands helps restore important Windows system files, which might be causing the driver error.

Step 4: Roll Back Recent Driver Updates

If the NVHDA64V-SYS error started after a recent driver update, rolling back to a previous version can help.

  1. Open Device Manager again (Windows + X > Device Manager).
  2. Locate the problematic device under Sound, video and game controllers or related categories.
  3. Right-click the device and choose Properties.
  4. Go to the Driver tab and click Roll Back Driver.
  5. Follow the instructions and restart your PC.

This step is important because sometimes new driver versions can introduce bugs or compatibility issues.

Step 5: Disable or Remove Conflicting Software

Third-party software, especially audio enhancement utilities or hardware management tools, may conflict with system drivers.

  • Think about any new software installed recently related to audio or system optimization.
  • Try temporarily disabling or uninstalling these programs.
  • Restart your computer and check if the NVHDA64V-SYS error persists.

Conflicts between software and drivers can cause system crashes or errors, so eliminating these conflicts can restore stability.

Alternative Method: Perform a Clean Boot

If you suspect startup programs are causing the issue, performing a clean boot can help identify the culprit.

  1. Press Windows + R, type msconfig, and press Enter.
  2. Go to the Services tab, check Hide all Microsoft services, then click Disable all.
  3. Next, switch to the Startup tab and click Open Task Manager.
  4. Disable all startup items.
  5. Close Task Manager and click OK in the System Configuration window.
  6. Restart your PC and see if the error still appears.

This method reduces software conflicts by running Windows with minimal programs.
