Fixing win32kfull.sys’ BSOD in Windows

Fixing win32kfull.sys BSOD in Windows

win32kfull.sys: A blue screen is a bad sign for Windows users. The computer will shut down and then resume normal operation.

Win32kfull.sys provides secure communication between a device and the Windows OS. The system could experience a BSOD error if communication between the core components is compromised. The system might indicate that win32kfull.sys is the problem.

What is the cause of win32kfull.sys failed BSOD error?

Before we move on to the solutions, let’s take a look at the possible reasons why win32kfull may fail. There are many reasons why this can happen, as we have already discussed. Older or incompatible drivers can cause common problems in all PCs.

Other than this. Here are other reasons win32kfull.sys files fail.

  • Bad memory module
  • Files from a corrupted system
  • Malware has affected the file
  • Failed Windows Update

All win32kfull.sys blue screen stop codes

The win32kfull.sys file can cause more serious Windows processes to fail. The PC will then give a BSOD error and a variety of STOP CODE. These are some possible stop codes that may be displayed when a Win32kfull.sys fails.

How do I fix win32kfull.sys failed BSOD error?

We have already discussed a method to find the source of the blue screen using Event Viewer before we move on to the solution. If you’ve already used Event Viewer, you can skip to the next step.

Event viewer

The event viewer tracks all events that the system encounters. It keeps track of all errors within the system. It is best to assume that the system can be accessed from the blue screen and that the event caused the problem.

  • You can check the event viewer here
  • To open Run, press the Windows + R key.
  • Type eventvwr, and hit Enter to open Event Viewer.
  • Scroll to the leftmost panel and go to Windows logs > system.

You can now see all events in your system by clicking on the middle panel.

The Source column should be checked. The Source column should contain Bug Check and the Event ID columns that say 1001 is the code for the blue screen.

To determine the exact cause of the error, you can check the events that occurred in the area around the blue screen.

It is important to remove any applications that are causing the error. To determine the exact cause, you can use dump files.

Disable Driver Verifier

Microsoft official documentation states that Driver Verifier inspects Windows drivers and kernel-level drivers for any illegal function calls that could cause system corruption. Windows drivers can be subjected to stress tests to identify any abnormal behavior. This could lead to a blue screen error.

  • To verify if the BSOD error is fixed, disable Driver verifier.
  • To open Run, press the Windows + R key.
  • Type verifier.exe into Open Driver Verifier Manager.
  • Check Delete existing settings.
  • Click on Finish.
  • Now, reboot your computer.
  • You can also use the command prompt for driver verification to be disabled.
  • Run Command prompt as administrator.
  • Type verifier/reset in the box below and hit Enter.
  • Restart your computer.

Take a look at the Memory Module

To allow the processor access the OS (or system files), it must be loaded into your RAM. If your RAM is defective, files that are responsible for running Windows might not be accessible, leading to a blue screen error.

  • To verify this, you will need to test the memory module. To determine if your memory is defective, you can use the Memory Diagnostic Tool.
  • Use the Window + R key for Open Run.
  • Enter MdSched, and hit the Enter key.
  • Click on Restart Now to check for issues (recommended).

Your memory will be tested by the PC. The RAM sticks may be the problem if the PC reports problems. You can test this by using only one RAM stick at once. Replace the RAM stick with a working one and check if the problem persists. Follow these steps to access RAM on your system.

  • Unscrew all screws connecting the side panel to your motherboard.
  • The CPU socket is usually located near RAM slots. The RAM sockets have locks on both ends.
  • To remove one RAM stick, pull the lock inwards.
  • Turn on the computer to verify that it is running without BSOD.
  • Warning! Removing a RAM stick can cause performance problems.

You can run the SFC command since wun32kfull.sys represents a system file. SFC (or the System File Checker command) checks for integrity and repairs all system files. The DISM (Deployment Image Servicing & Management) allows admins to scan and fix Windows Image.

  • To open Run, press the Windows + R key.
  • Enter cmd, and hit Ctrl + Shift+ Enter to Open Command Prompt As Administrator.
  • To repair the system image, type DISM/Online/Cleanup/RestoreHealth then press Enter.
  • To run the SFC command, type SFC /scannow. Wait for the command’s processing to complete.

Storage Devices

Random bad sectors and corrupted data may occur in the Storage device. These issues can cause BSODs that are frequent and random in storage devices with OS. You can check that the storage device isn’t defective by running the Check Disk command.

  • Use the Windows + R key for Open Run.
  • Enter cmd, and then press Ctrl+ Shift + Enter to open Command Prompt .
  • Enter chkdsk C: /f
  • Next, press y and finally press Enter.
  • Once the computer restarts, the Check Disk command will be run on the C drive.
  • /f corrects any errors on your disk.
  • /r finds bad sectors and attempts to recover data from them.

Make sure to clean your boots

Third-party apps can run their own services. This may cause conflicts with Windows services. If Windows encounters a problem that prevents critical processes from running, the system will display a red screen error. To determine if the problem is caused by a third-party program, try a clean boot.

  • To perform a clean boot,
  • Use the Windows + R key for Open Run.
  • Enter msconfig, and hit the enter key to Open System Configuration.
  • Go to the Services tab.
  • Check Hide all Microsoft Services and choose Disable All.
  • Click on Use.
  • Go to the Startup tab, and click on Task Manager.
  • Click on an app and choose Disable.

All applications that are running at startup should be disabled

Check if your computer boots normally by restarting it

Update/Reinstall Driver

Older drivers or corrupted drivers might not be able to communicate with the OS effectively. This could cause problems for the OS to transfer data to its device. In this case, the OS may have trouble managing memory due to corrupted drivers. This can be fixed by updating the device drivers.

  • Use the Windows + X key to open the Device Manager .
  • Expand any of the device collections.
  • Right-click any device with an exclamation point and select the Update driver.
  • Click on Search for drivers automatically. Wait for the update process to complete.
  • If the driver update does not work, right click on the device and choose Uninstall Device.
  • To reinstall the driver, restart your computer.
