The emergence of the Purple Screen of Death, or PSOD, has added another layer of fear for Windows users, alongside the infamous Blue Screen of Death. The presence of these error screens is closely tied to the Windows operating system, making it feel incomplete without them.

 However, setting jokes aside, let us delve into one of the critical BSOD errors encountered by Windows users. Today, we will address the PNP_DETECTED_FATAL_ERROR, an issue that unexpectedly arises and causes a system shutdown after displaying a Blue Screen.

 

What is PNP_DETECTED_FATAL_ERROR on Windows?

 Prior to delving into the root cause of the error encountered on Windows, it is crucial to acknowledge that this particular error is frequently linked with various other stop codes, including 0x000000CA (0x01681690, 0xEA96A7BE, 0x938A81AD, 0xF8362881).

 The PNP DETECTED FATAL ERROR on Windows is typically triggered when the operating system is unable to identify a suitable driver for the connected Plug and Play devices. 

If you have recently added a plug-and-play hardware component to your computer and Windows is unable to locate the necessary driver, you may encounter the Blue Screen of Death (BSOD). This error can also occur as a result of incompatible, outdated, or damaged driver files, highlighting the importance of addressing driver-related issues. Therefore, troubleshooting efforts should primarily focus on resolving driver-related issues. If resolving driver problems does not resolve the error, you may consider attempting the following solutions.

• Reconnect the newly installed hardware.
• Disable the BIOS Memory Options.
• Update all Device Drivers.
• Run the Disk Check Utility.
• Check and rule out the hardware issues.
• Perform a System Restore.

It is possible that you encountered this error after installing new hardware, such as a webcam, microphone, mouse, keyboard, or any other device. To determine if the hardware is causing the error, you should temporarily remove it and observe if the error persists.
  
  If the error is resolved and no longer appears after removing the hardware, then you have identified the culprit.
