Solved: INTERRUPT UNWIND FAILED (0X00000047) BSOD Crash on Windows 10/11

The INTERRUPT UNWIND FAILED (0x00000047) Blue Screen of Death (BSOD) is a frustrating error that can occur in Windows 10 or 11, often leading to system crashes. This error typically appears when the operating system encounters an issue during the unwinding of interrupt requests, which are signals sent between hardware and software components. While this error doesnt happen frequently, it can disrupt your workflow and cause data loss if not addressed promptly. Below, well explore what causes this BSOD, how to diagnose it, and provide step-by-step solutions to resolve it.

What Causes the INTERRUPT UNWIND FAILED (0x00000047) Error?

The INTERRUPT UNWIND FAILED error is usually triggered by hardware or driver-related issues, particularly those involving:

  • Faulty or outdated drivers, especially graphics, network, or storage controllers.
  • Corrupted system files due to improper shutdowns, malware, or disk errors.
  • Hardware conflicts, such as faulty RAM, a failing hard drive, or overheating components.
  • Incompatible software or drivers that conflict with Windows core processes.
  • Overclocking or BIOS/UEFI misconfigurations

    (common in gaming PCs).

The error may also appear after installing updates, running intensive applications, or during system startup. If you see this BSOD, your PC will restart automatically, and an error log is generated in the %SystemRoot%\Minidump folder (e.g., MEMORY.dmp). Analyzing these logs can help pinpoint the root cause.

How to Fix INTERRUPT UNWIND FAILED (0x00000047) BSOD

### **Method 1: Run System File Checker and DISM**
Corrupted system files are a common culprit. Use Windows built-in tools to repair them:

  • Press Win + X, then select Terminal (Admin) or Command Prompt (Admin).
  • Run the following commands one by one, pressing Enter after each: 
    DISM /Online /Cleanup-Image /RestoreHealth
    sfc /scannow
  • Restart your PC and check if the issue persists.

### **Method 2: Check for Disk Errors with CHKDSK**
A failing hard drive or bad sectors can trigger this error. Run CHKDSK to scan and repair disk issues:

  • Open Command Prompt (Admin).
  • Type the following command and press Enter: 
    chkdsk C: /f /r /x

    (Replace C: with your system drive if needed.)

  • If prompted, confirm to run the scan on the next reboot.
  • Wait for the process to complete and restart your PC.

### **Method 3: Update or Reinstall Problematic Drivers**
Outdated or conflicting drivers (especially GPU, chipset, or storage) often cause this error:

  • Press Win + X, then select Device Manager.
  • Expand categories like Display adapters, Storage controllers, and Network adapters.
  • Right-click each device, select Update driver, then choose Search automatically for drivers.
  • If no updates are found, use the manufacturers website (e.g., NVIDIA, AMD, Intel) to download the latest drivers.
  • Alternatively, roll back drivers by right-clicking a device Properties Driver tab Roll Back Driver.

### **Method 4: Test and Replace Faulty RAM**
Faulty RAM can cause intermittent BSODs. Use Windows Memory Diagnostic:

  • Search for Windows Memory Diagnostic, open the tool, and select Restart now and check for problems.
  • Follow on-screen instructions to complete the scan.
  • If errors are found, replace or reseat your RAM modules.

### **Method 5: Check for Overheating or Hardware Issues**
Overheating can trigger this error. Monitor temperatures using tools like HWMonitor and ensure:
– CPU/GPU temperatures stay below 80C under load.
– Fans are functioning properly (clean dust from vents).
– Reapply thermal paste if overheating persists.

### **Method 6: Disable Overclocking or Adjust BIOS Settings**
If youve overclocked your CPU/GPU, reset to default settings in BIOS/UEFI:
1. Restart and enter BIOS (usually by pressing Del, F2, or Esc during boot).
2. Look for Overclocking or Performance settings and reset them to default.
3. Save changes and exit.

### **Method 7: Perform a Clean Boot**
A conflicting startup program may trigger the error:
1. Press Win + R, type msconfig, and press Enter.
2. Go to the Services tab, check Hide all Microsoft services_, then click Disable all.
3. Go to the Startup tab, click Open Task Manager, and disable all startup items.
4. Restart your PC in a clean state. If the error doesnt occur, re-enable items one by one to identify the culprit.

### **Method 8: Check for Windows Updates**
Microsoft releases patches that fix BSOD-related bugs:
1. Go to Settings Update & Security Windows Update.
2. Click Check for updates and install any pending updates.
3. Restart your PC afterward.

### **Method 9: Use System Restore (If Applicable)**
If the error started after a recent change, restore Windows to an earlier point:
1. Search for Create a restore point, go to System Protection_, and click System Restore.
2. Follow the prompts to choose a restore point before the issue began.

### **Method 10: Reinstall or Reset Windows (Last Resort)**
If all else fails, reinstall Windows:
– Back up your data, then use Settings Update & Security Recovery Reset this PC.
– Choose Keep my files to preserve personal data.

FAQ: Common Questions About INTERRUPT UNWIND FAILED (0x00000047)

Q: Is this error hardware or software-related?
A: Its often caused by bothfaulty drivers, corrupted files, or hardware issues like RAM or overheating. Diagnose with the steps above to narrow it down.

Q: Can I prevent future BSODs after fixing this?
A: Yes! Regularly update drivers, scan for malware, monitor temperatures, and avoid overclocking unless necessary. Use tools like Windows Update to stay patched.

Q: Why does this error appear during gaming?
A: Gaming stresses hardware (GPU/RAM), which may expose instability. Ensure your drivers are updated and check for overheating or faulty GPU connections.
