Causes of Ntoskrnl.exe blue screen errors

The Ntoskrnl.exe error can have several causes.

Since this error is memory related, it can also be caused by bad RAM.

Here are some troubleshooting tips for the ntoskrnl.exe BSOD:

Use Windows Memory Diagnostics

The BSOD can be associated with a faulty memory (RAM) module. So, here’s what you need to do:

  • Close all open windows.
  • Go to the start menu.
  • Enter “Windows Memory Diagnostics” in the search bar and click the option when it appears in the list of results.
  • Click on the option “Restart now and check for problems (recommended)”.
  • Your system will reboot and scan will begin. Wait for the process to complete. This can take a while (it can take up to an hour depending on how much memory you have).
  • After scanning, you will receive the results as soon as you log into your computer.

Updating Drivers

A good rule of thumb to determine if this might be causing the problem is to ask yourself when was the last time you updated your drivers. If you don’t know or don’t remember it, expired drivers could be the cause.

And even if they are not the cause, you still need to update them, because outdated drivers can cause all sorts of problems. In fact, you should make sure your drivers are updated regularly.

Reset your devices overclocking settings

While overclocking is a smart way to get the most out of your hardware, it can also lead to overheating, hardware failure, and system crashes. Stop overclocking your devices if you encounter Ntoskrnl.exe error.

You can use an approved program to change the settings. But you can also do it via BIOS / UEFI. The procedure is different for each device. So read the instructions on how to do it.

Refresh your Computer

Make sure your computer has the latest Windows updates. Please note that running outdated versions of the operating system can cause various problems on your device, including BSOD errors caused by ntoskrnl.exe.
