What is the cause of the DRIVER PNP WATCHDOG error?

What is the cause of the DRIVER PNP WATCHDOG error?

After a thorough analysis of user reports, we were able to conclude that this error may be caused by software issues. Some of these issues are:

Incorrect SATA controller settings in the BIOS: The SATA controller has several modes such as IDE, AHCI, etc. If the SATA controller mode is not properly set in the BIOS, it may cause this error.

Malicious infections: A system infected with viruses/malware can only suffer from many errors, as this infection can make many important files/services behave incorrectly, which in turn can lead to this problem.

Antivirus and firewall problems: Antivirus software can also block important system components and services. When they are blocked, they can’t access the necessary files, leading to BSODs.

Volume Shadow Service: when VSS backs up, it locks the file/disk as read-only, and if VSS does not start correctly or loops, it can restrict access to the file/disk, which can lead to this error.

Faulty system services: Windows system services are key components of the operating system and if one of the system files is faulty, BSOD will occur.

Damaged system files and disks: Updated system files/drivers are required for the system to work properly. If they are corrupted, this error may be caused.

RAM problems: RAM problems are not as common as other computer problems. RAM usually lasts longer than other computer components, but if RAM is having trouble performing its functions, it can cause this problem.

Faulty drivers: device drivers communicate between the device and the operating system, and if the device driver has failed, this can be the cause of the problem.

Outdated device drivers: Outdated device drivers can cause many problems for the correct functioning of the system, as technology is constantly and rapidly changing. If the device drivers are not updated with the new technology, these outdated drivers can cause this particular system error.

Inconsistent Update: Microsoft has a long history of updating Windows, and it is possible that one of these updates could be causing this problem.

Windows Update problem: If Windows Update was updating the system but failed to complete its work, it may cause a PNP watchdog driver BSOD.

Outdated operating system: Microsoft releases new updates to fix Windows flaws. If Windows is outdated, it may have many flaws that can cause this problem.

Installing corrupted Windows: Although with improvements in technology Windows is quite resistant to corruption compared to Windows ten years ago, it can still be corrupted, and this corruption can lead to this particular error.


How to fix the DRIVER PNP WATCHDOG error?

How to fix the DRIVER PNP WATCHDOG error?

Perform a full system analysis

Viruses and malware can cause driver PNP watchdog errors, so you should scan your Windows 10 PC for viruses and malware to remove them. You can either use Windows Defender, a built-in Windows antivirus program, or a third-party antivirus program to perform a full system scan.

In the meantime, if you still get PNP Watchdog driver error when running Windows Update, you can go for the following solution.

PC registry restore

Due to various problems, system files can get corrupted, which causes the Windows registry to become corrupted. However, sometimes the Windows registry can also get bloated, resulting in PNP Watchdog Driver error.

Therefore, you need to restore the Windows registry using the System File Checker (SFC) utility. The System File Checker utility checks all system files for accuracy and restores files with problems if possible.

To perform an SFC scan under Windows 10 :

  1. Go to the Start menu -> type cmd -> right-click the command line -> select Run as administrator.
  2. Now enter the command sfc / scan now.
  3. Wait until the scanning process is complete and then restart your computer. Any corrupted files will be replaced on reboot.

In addition to running the SFC scan, you can also use DISM to resolve the BSOD watchdog PNP driver problem. Deployment Image Maintenance and Management is a tool that is also used to analyze and resolve issues related to corrupted system files.

To run DISM in Windows :

  • Press the Windows + X keys and run the command prompt (Admin).
  • Copy and paste the following command to the command prompt :
    exe /Online /Cleanup-image /Restorehealth.
  • If DISM cannot retrieve files on the Internet, try using USB or the installation DVD. Insert the media and enter the following command:
    DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess
  • Be sure to replace the path “C: RepairSourceWindows” with the path of your DVD or USB flash drive.

Note: Make sure you replace the recovery source path with your own.

CHKDSK direction

Some Windows 10 users may have fixed the PNP Watchdog BSoD driver problem by running CHKDSK on their hard drive. Unwanted files or folders taking up your space can also cause a PNP Watchdog BSoD driver error, so you should free up your hard drive.

Follow these steps:

  1. Go to the Start menu -> Type “Command Prompt” -> Right-click on it and select “Run as administrator”.
  2. Now type CHKDSK C: /F.
  3. Then type CHKDSK C: /R at the command prompt and press Enter.
  4. Restart your computer after the CHKDSK process is complete.
Using a third-party registry cleaner

A third-party registry cleaner is an automated solution that can be used to solve the PNP driver watchdog BSoD problem. This tool removes missing DLLs, software remnants, and invalid Windows registry keys.

You can also use a third-party registry cleaner to fix the Windows registry and make it error-free. It also has a number of other great features. You can always get BSoD monitoring PNP for drivers; you can switch to the following method.

Updating the system driver

Outdated system pilots can cause system errors and, in particular, PNP pilot watchdog BSoD errors. In addition, PNP driver watchdog errors are “driver-related”, so you may need to update all system drivers without using Windows Update. This happens because there is a problem with the PNP driver watchdog BSoD when running Windows Update.

In short, you must use third-party programs to update old system drivers.

Performing an automatic repair

You can also repair the BSoD Driver PNP watchdog by performing an automatic repair. However, you may need a Windows bootable installation DVD to do this.

Some Windows users have reported that they were able to fix the BSoD driver for the PNP watchdog simply by installing the Microsoft patch.

Follow these steps:

  1. Call Microsoft support.
  2. Now click on the available Hotfix download menu
  3. Once downloaded, install the patch by following the instructions.
  4. Then reboot your computer.
Run the diagnostic program for Windows Updates

The Windows 10 operating system has several diagnostics to solve various problems. To solve the BSoD Watchdog PNP driver problem that occurs during a Windows update, we recommend using the Windows Update diagnostic program.
