Solved: tcpip.sys BSOD Crash on Windows 10/11

The tcpip.sys file is a critical system driver in Windows responsible for managing network communication. When this driver encounters issues, it can trigger the dreaded Blue Screen of Death (BSOD), often with error codes like CRITICAL_PROCESS_DIED, KERNEL_SECURITY_CHECK_FAILURE, or SYSTEM_SERVICE_EXCEPTION. If you’re experiencing frequent crashes related to this file, follow these steps to diagnose and resolve the problem.

Why Does tcpip.sys Cause BSODs?

The tcpip.sys driver handles TCP/IP protocol operations, including network traffic, IP addressing, and data transmission. A BSOD related to this file typically occurs due to:

  • Corrupt or outdated network drivers: Outdated or poorly written drivers can conflict with the system.
  • Malware or virus infections: Some malware targets network components, leading to instability.
  • Hardware issues

    (e.g., faulty RAM, overheating, or failing storage).

  • Windows updates or driver conflicts: A recent update may have introduced bugs or compatibility issues.
  • Corrupted system files: System file corruption can disrupt core Windows operations.

Step-by-Step Fixes for tcpip.sys BSOD

1. Run System File Checker (SFC) and DISM

Corrupted system files are a common cause of driver-related crashes. Use Windows’ built-in tools to repair them:

  • Open Command Prompt as Administrator:
    • 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.

2. Update or Reinstall Network Drivers

Outdated or faulty drivers can trigger BSODs. Heres how to fix them:

  • Open Device Manager by pressing Win + X and selecting it.
  • Expand Network adapters, right-click your active network card, and choose Update driver.
  • Select Search automatically for drivers. If no updates are found:
    • Visit the manufacturers website (e.g., Intel, Realtek) to download the latest driver manually.
    • Right-click the network adapter again and choose Uninstall device, then restart your PC. Windows will reinstall it automatically.

3. Check for Malware

Malware can corrupt system files, including tcpip.sys. Run a full scan using:

  • Open Windows Security (search in the Start menu).
  • Go to Virus & threat protection > Quick scan.
  • For deeper scans, use Microsoft Defender Offline Scan or third-party tools like Malwarebytes.

4. Test for Hardware Issues

Faulty RAM or overheating can cause random BSODs. Diagnose with:

  • RAM Test: Use Windows Memory Diagnostic: 
    mdsched.exe

    Select Restart now and check for problems.

  • Storage Check (CHKDSK): Run in Command Prompt (Admin): 
    chkdsk C: /f /r

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

  • Monitor temperatures using tools like HWMonitor to rule out overheating.

5. Roll Back or Disable Problematic Updates

If the issue started after a Windows update:

  • Go to Settings > Update & Security > Windows Update > View update history.
  • Click Uninstall updates and remove recent ones.
  • Alternatively, use System Restore (search for it in the Start menu) to revert to a stable state before the crashes began.

6. Check Event Viewer for Clues

Event Viewer logs can pinpoint the exact cause:

  • Press Win + X, then select Event Viewer.
  • Navigate to Windows Logs > System and look for errors with tcpip.sys in the details.
  • Note any error codes (e.g., 0xD1) and search online for solutions specific to them.

7. Reset TCP/IP Stack (Advanced)

Reset network settings if corruption persists:

  • Open Command Prompt as Admin and run: 
    netsh int ip reset reset.log
    ipconfig /flushdns
  • Restart your PC.

FAQ: Common Questions About tcpip.sys BSODs

Q: Will a clean Windows install fix this?

A: Yes, but try the steps above first. A clean install should resolve persistent issues if no hardware faults exist.

Q: Can third-party antivirus cause this?

A: Rarely, but some security software may conflict with tcpip.sys. Try temporarily disabling it to test.

Q: Why does this happen only on Wi-Fi?

A: Faulty Wi-Fi drivers or router firmware can trigger BSODs. Update both your adapter and routers firmware.

Q: Is there a way to prevent future crashes?

A: Yeskeep Windows updated, avoid pirated drivers, and use trusted security software. Regularly scan for malware and monitor hardware health.

Final Notes

If none of these steps work, the issue may stem from a failing hard drive or motherboard. Contact Microsoft Support or your PC manufacturer for further assistance. Most users resolve tcpip.sys BSODs with driver updates and system file repairsstart there before considering deeper troubleshooting.
