How to Fix PNP Detected Fatal Error in Windows 10?

If you cannot boot Windows due to a PNP-detected fatal error, then it is recommended that you start your system in Safe Mode, unplug peripheral devices such as USB, pendrive, printer, etc., and then proceed to follow the solutions one by one.

Solution 1: Run the BSOD Troubleshooter

First of all, here it is suggested to run the inbuilt BSOD troubleshooter; it scans your system completely and fixes issues, generating the stop code PNP DETECTED FATAL ERROR. This tool has been used by many users to fix blue screen of death error codes.

Follow these steps to run the troubleshooter.

  • Click on Update and Security after you have opened Settings.
  • Click on Troubleshoot from the menu to the left.
  • Click on Run Troubleshooter after selecting BSOD.
  • Wait for the scan to finish.

Restart your computer and see if you can fix the problem.

Solution 2: Perform System Restoration

It is recommended that you perform a system restore if the BSOD troubleshooter does not work. This will return your system to a previous state, where no errors were present.

Follow these steps to restore your system:

  • In the Run window, type rstrui.exe, and then hit Enter.
  • Click on the Next icon in the Restore System window.
  • Click Next to select a previous time when the system was working well.
  • Click on Finish.
  • Wait for your computer to finish.

I hope now you can run the system without seeing the BSOD PNP_DETECTED_FATAL_ERROR.

Solution 3: Update Drivers

If you still see the fatal error after updating Windows 10, then it is likely that the system drivers have not been updated or are incompatible. This will result in the Blue Screen of Death error.

Visit the Microsoft website or the manufacturer’s website and search for updates.

Take the following steps:

  • Type Devmgmt.msc in the Run box and press Enter.
  • In the device manager, look for outdated drivers (marked with a small exclamation point).
  • Click on the driver, and then choose Update Driver from the menu.
  • Click on Find updated drivers automatically.
  • Reboot your computer after the scanning process is complete.

You can update drivers automatically by using the Driver Updater tool. It will scan your system and update all drivers.

Solution 4: Update Windows 10

The latest Windows updates not only improve the performance of the system but also include patches and bug fixes, such as the one in question.

Windows 10 updates are usually installed automatically, but you may miss an update if there is a problem or error.

Check for updates manually. To do this, follow these steps:

  • Open the Settings application by pressing Windows Key + the I key.
  • Go to the Update and Security section.
  • Click Updates to check for the latest updates.

Windows will now start scanning for updates and downloading them automatically. Restart your computer after the updates have been downloaded. Verify if the problem has been fixed.

Solution 5: Restore corrupted Windows system files

The corrupted Windows system files can also cause conflict and result in showing the stop code PNP DETECTED FATAL ERROR in Windows 10.

Here is a suggestion: run the System File Checker Command and fix the corrupted Windows system files.

Take the following steps:

  • Open Command Prompt as Administrator by typing CMD in the search box.
  • Type scannow in the command prompt, and then press Enter.
  • Wait until the scanning process is complete (approx. 15 minutes).

And as soon as the scanning process is finished, restart your computer and check if the BSOD PNP_DETECTED_FATAL_ERROR is fixed or not.

Solution 6: Check your hardware

Check if any new hardware has been installed recently. This could be the cause of the blue screen.

Add more RAM if you find that your RAM is not working properly. Check other components, such as the motherboard and hard drive.

If you’re not technical, then this isn’t the solution for you.
