Fixing DATA CACHING ERROR (0X00000055) Stop Code on Windows 10 & 11 Step by Step

The **DATA CACHING ERROR (0x00000055)** stop code, also known as a Blue Screen of Death (BSOD), can appear unexpectedly and disrupt your workflow. This error typically occurs when Windows fails to access or cache data properly, often due to hardware issues, corrupted system files, or driver conflicts. While frustrating, this issue is usually fixable with the right steps. Below, well guide you through identifying the cause and resolving it effectively.

What Causes the DATA CACHING ERROR (0x00000055)?

The 0x00000055 error can stem from several underlying issues:

  • Corrupted system files or registry entries.
  • Faulty or outdated drivers, especially those related to storage (e.g., disk controllers, SSDs, or RAM).
  • Hardware problems**, such as failing RAM modules, overheating, or loose connections in your system.
  • Malware or virus infections** that interfere with core Windows processes.
  • Incompatible software or drivers** installed recently (e.g., graphics card drivers).
  • Disk errors or bad sectors on your storage drive.

If you experience this error frequently, its best to address it promptly to prevent data loss or further system instability.

Step-by-Step Fixes for the 0x00000055 BSOD

Method 1: Run System File Checker (SFC) and DISM

The first step is to repair corrupted system files using built-in Windows tools. These commands scan and restore critical system components.

  • Open Command Prompt as Administrator:
    • Press Win + X, then select **Terminal (Admin)** or **Command Prompt (Admin)**.
  • Run SFC Scan: In the command prompt, type the following and press Enter: 
    sfc /scannow

    Wait for the scan to complete. If errors are found, they will be repaired automatically.

  • Run DISM (Deployment Image Servicing and Management): Type the following command and press Enter: 
    DISM /Online /Cleanup-Image /RestoreHealth

    This may take several minutes. Restart your PC afterward.

Method 2: Check for Disk Errors with CHKDSK

If the issue is related to disk corruption, run CHKDSK (Check Disk) to scan and fix errors.

  • Open Command Prompt as Administrator: As before, use Win + X > **Terminal (Admin)**.
  • Run CHKDSK: Type the following command and press Enter: 
    chkdsk C: /f /r

    Replace C: with your system drive letter if needed. If prompted, schedule the scan for the next reboot.

  • Restart your PC** and let the scan complete.

Method 3: Update or Roll Back Drivers

Outdated or conflicting drivers (especially storage-related) can trigger this error. Heres how to update them:

  • Open Device Manager: Press Win + X, then select **Device Manager**.
  • Expand “Disk drives” or “Storage controllers.”** Look for devices with a yellow warning icon (e.g., SATA/RAID controllers).
    • Right-click the device > **Update driver** > **Search automatically for drivers**.
    • If no updates are found, try rolling back the driver:
      • Right-click the device > **Properties** > **Driver** tab.
      • Click **Roll Back Driver**, then restart your PC if prompted.

Method 4: Test Your RAM and Storage Hardware

Faulty RAM or a failing hard drive/SSD can cause this error. Test them using these steps:

  • Test RAM with Windows Memory Diagnostic:**
    • Press Win + R, type mdsched.exe, and press Enter.
    • Select **Restart now and check for problems**.
    • Follow the on-screen instructions. If errors are found, replace or reseat your RAM sticks.
  • Check Disk Health (for SSDs/HDDs):**
    • Open **File Explorer**, right-click your system drive > **Properties** > **Tools** tab.
    • Under **Error checking**, click **Check**.
    • Select both options (**Automatically fix file system errors** and **Scan for bad sectors**), then click **Scan now**.

    Method 5: Uninstall Problematic Software or Drivers

    If the error started after installing new software, uninstall it:

    • Open Settings** > **Apps** > **Apps & features**.
    • Sort by **Install date**, then look for recently installed programs.
      • Select the suspicious app > **Uninstall**.
      • Restart your PC afterward.

    Method 6: Run a Full Malware Scan

    Malware can corrupt system files. Use Windows Defender or third-party antivirus to scan your system:

    • Open Windows Security** > **Virus & threat protection**.
    • Click **Quick scan** (or **Full scan** for thorough checking).
      • Follow the prompts to quarantine or remove threats.
      • Restart your PC if required.

    Method 7: Reset Windows (Last Resort)

    If all else fails, a clean install of Windows may be necessary. Back up your data first, then:

    • Go to Settings** > **Update & Security** > **Recovery**.
    • Under **Reset this PC**, choose **Get started** and follow the prompts.
      • Select **Keep my files** (if you want to preserve data) or **Remove everything**.
      • Follow the on-screen instructions to complete the reset.
