BSOD (Blue Screen of Death) errors are not new in Windows, and ntkrnnlmp.exe is among one of them. Typically this error is caused due to the corruption of the graphics card driver on your system. However, a virus or malware can also be the cause behind it.

ntkrnlmp.exe stands for NT Kernel Multi Processor version. It is a system file that manages kernel files of the OS and hence, can be deemed as a very critical file. Interestingly, when the BSOD error ntkrnlmp.exe is mentioned, it does not mean the process itself is causing the issue but that the process had bad/bogus data that caused the crash.

Since the error has crept its way from Windows 7 to Windows 11, the error is documented enough to have plenty of methods to resolve it. However, do note, you might have to try more than one method listed in this guide.

Common Culprits for ntkrnlmp.exe BSOD Error

Though it is generally difficult to identify the cause for the ntkrnlmp.exe BSOD error, listed below are the known causes for it as per documented events.

  • Incompatible, outdated, or corrupted graphics driver.
  • A corrupted RAID controller.
  • It is caused due to a bad Windows Update.
  • C-States and EIST are enabled in the BIOS and are creating a ruckus when the PC is idle.
  • A bad power adapter is causing a voltage issue when the PC changes states (going from idle to stress or vice versa).
  • Two non-identical RAM sticks are installed in the PC with varying timing.

1. Update or Reinstall Graphics Driver

Since the issue is typically caused due to an outdated or corrupt graphics driver, it makes sense to perform this fix first before hopping onto any other method. You can either update it from the Settings app, Device Manager, or choose to force reinstall.

To update the driver using the Settings app, head to the Start Menu and click on the ‘Settings’ tile.

Then, head to the ‘Advanced’ tab and click or highlight the ‘Power Technology’ option.

Now, highlight the ‘Intel EIST’ option using the Arrow keys and press Enter to disable it. Repeat the step for the ‘Intel C-State’ option.

Once done, save the changes and exit the BIOS setup by pressing the key displayed on the screen. Usually, the F4 key is associated with saving the changes and exiting the BIOS.

Once done, log in to your user account and check if the issue has been resolved.

4. Use Driver Verifier

Driver verifier, as the name suggests is a built-in utility that allows you to check for malfunctioning drivers among the installed ones on your PC. It is simple and efficient to diagnose any driver-related issues using Driver Verifier.

Head to the Start Menu and type Terminal to perform a search. Then, from the search results, right-click on the ‘Terminal’ and click on the ‘Run as administrator’ option.

After that, a UAC (User Account Control) window will appear on your screen. If you are not logged in with an admin account, enter the credentials for it. Otherwise, click on the ‘Yes’ button to proceed.
