The BSOD INVALID KERNEL HANDLE error indicates that an invalid or protected handle was passed to NtClose. Usually faulty hardware or corrupt operating system files are the main cause of this particular blue screen error.

In addition to this, wrong entries in the registry or a failed Windows update can be the reason why you are getting an INVALID KERNEL HANDLE ERROR. To fix this problem, we have listed some of the solutions that might fix the BSOD INVALID KERNEL HANDLE error on your PC.

What is an INVALID KERNEL HANDLE error and what causes it?

Below we have listed a few reasons why you may encounter an INVALID KERNEL HANDLE error.

  • Corrupt system files
  • Damaged RAM
  • Bad sectors on the drive containing the operating system
  • Outdated driver
  • Incorrect registry values
  • Outdated version of Windows


Some of the headings explained below are troubleshooting steps. These steps may not fix the problem, but they will give you some insight into what is causing the blue screen. First, let’s start with the Event Viewer.

Run Event Viewer

Event Viewer records everything that happens in your system in great detail. Using this, you can check what exactly caused the INVALID KERNEL HANDLE error. Once you get a blue screen, Event Viewer logs it by Bug check source name, and its EventID is 1001.

To run Event Viewer,

  1. Press Windows key + R to open Run.
  2. Type eventvwr and press Enter to open Event Viewer.
  3. In the leftmost panel, navigate to Windows logs > System.
  4. Now on the middle panel you can see the Level error, its date and time, The sourceand Event ID.
  5. To filter all events caused by the blue screen, in the rightmost panel, click Filter current log.
    filter current log
  6. Set event source to Bug check. And type 1001 on the box.
  7. Click on OKAY to display only events caused by the blue screen.

Once you have a general idea of ​​the reason for the INVALID KERNEL HANDLE error, you can try to fix the particular issue.

Test storage device

Corrupt or bad sectors on the hard drive containing the operating system can affect system and driver files, resulting in blue screen error. Hard drives use physical moving components and are susceptible to damage. Therefore, we recommend that you check the health of your hard drive from time to time.

To check the status of your hard drive,

  1. Press Windows key + R to open Run.
  2. Type cmd and press Enter to run the command prompt.
  3. Type wmic diskdrive get model,statusand press Enter to get the drive status.

If the status shows OK, your storage device is functional. The status will show Pred fail if your storage device is faulty. Moreover, if you want to check partition, you can also run Check Disk command to scan and repair bad sectors.

Check memory module

Your computer’s RAM is responsible for storing data that the processor needs while running an application. It also stores operating system and driver files once the system boots. If you have faulty memory, the processor may not be able to access required operating system files. This can cause the system to go into a blue screen state.

To check if this is true, you can try running the Memory Diagnostic Tool. The Memory Diagnostic Tool runs a series of tests to verify that your RAM sticks are working. Follow the steps mentioned below to run the memory diagnostic tool.

  1. Press Windows key + R to open Run.
  2. Type MdSched and press Enter to open the Windows Memory Diagnostic Tool.
  3. Click on Reboot now and check for issues (recommended).

Once the PC restarts, it will open a screen where it tests your PC’s memory and simultaneously gives you details about the scan. You can also use Event Viewer to check the scan report.

If Windows Memory Diagnostic gives you an error, you can use one USB drive at a time to determine the faulty memory. If you’re only using a single USB drive, you may need to replace the RAM.

Uninstall recently installed app

Applications that have access to hardware components and system files can also cause the INVALID KERNEL HANDLE error. Applications such as anti-virus software have full access to operating system and driver files. Likewise, third-party hardware monitoring apps have some level of access to hardware components.
