Root Cause & Diagnostic Breakdown

To fix Windows 11 Blue Screen error 0x50 (PAGE_FAULT_IN_NONPAGED_AREA), test your RAM modules for physical parity errors and reset the Windows virtual memory paging file. Bugcheck 0x50 happens when the kernel references memory that cannot be paged into RAM, typically indicating physical memory degradation, faulty RAM timings, or an NTFS file system structure error inside pagefile.sys. In our workbench tests, run mdsched.exe from the Run prompt to initiate a full hardware memory diagnostic pass. Next, navigate to Advanced System Settings, open Performance Options, click Virtual Memory, set Paging File Size to No paging file, restart your computer to delete the corrupted system file, and restore automatic page file management. If crashes continue, execute chkdsk C: /f /r in elevated PowerShell to repair damaged sectors.

Parameter 1 Minidump & Subsystem Telemetry

Underlying Trigger:
Invalid system memory was referenced. Memory addresses point to RAM that does not exist or has encountered hardware parity bit-flips, or an antivirus kernel filter driver requested illegal memory.
Parameter 1 Decoding:
Memory virtual address that was improperly accessed by the kernel thread.

4-Step Resolution Runbook

  1. Run Windows Memory Diagnostic (mdsched.exe) across all RAM modules.
  2. Clear corrupted pagefile.sys by disabling virtual memory paging, rebooting, and re-enabling.
  3. Run Check Disk (chkdsk C: /f /r) to scan NTFS volume structures.
  4. Roll back recently installed third-party antivirus filter drivers.
