What is the cause of the DRIVER PNP WATCHDOG error?

Based on user reports, we uncovered a number of software issues that may be contributing to this error:

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.

On rollbacks, OxC1900101 and Ox30018 are listed as errors for Driver PNP Watchdog

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Outdated device drivers: Outdated device drivers can cause many problems for the correct functioning of the system, as technology is constantly and rapidly changing. If the device drivers are not updated with the new technology, these outdated drivers can cause this particular system error.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 If Windows is outdated, it may have many flaws that can cause this problem.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

    In DISM.exe, choose “Online “, select “Cleanup-Image” and “RestoreHealth” and select “Limit Access”
