1. What Is PAGE_FAULT_IN_NONPAGED_AREA?

PAGE_FAULT_IN_NONPAGED_AREA is a Windows stop code that appears when the operating system cannot access a memory address that should be present in physical memory or otherwise accessible as expected.

Windows uses different types of memory to manage running applications, drivers, and system processes.

The nonpaged area is a portion of system memory that must remain available in physical RAM. It cannot be moved to the paging file when Windows needs it.

When a kernel-mode component attempts to access an invalid or unavailable memory address, Windows may stop operating and display a blue screen to protect the system.

You may see the following message:

Stop Code: PAGE_FAULT_IN_NONPAGED_AREA

The error may also display the code 0x00000050.

Sometimes, Windows identifies a related driver or system file on the blue screen. This information can help narrow down the cause.
