PAGE_FAULT_IN_NONPAGED_AREA Fix: Step-by-Step Guide for Windows 11

Experiencing a PAGE_FAULT_IN_NONPAGED_AREA BSOD on Windows 11 can be alarming. This error usually points to memory-related issues or driver problems that prevent your system from functioning. Unlike simple application crashes, this BSOD stops Windows entirely, making troubleshooting crucial.

In this guide, we’ll cover:

• Root causes
• Preventive strategies
• Step-by-step fixes to restore system stability

What Is PAGE_FAULT_IN_NONPAGED_AREA?

The PAGE_FAULT_IN_NONPAGED_AREA error occurs when Windows tries to access a part of memory that shouldn’t be paged to disk. Essentially, the system requests a critical memory segment that is either unavailable or corrupted.

Common triggers include:

• Faulty RAM modules or memory instability
• Corrupt or outdated device drivers
• Conflicts caused by antivirus or system utilities
• Disk corruption affecting nonpaged system memory

This error is closely related to other memory-related blue screen errors, such as MEMORY_MANAGEMENT BSOD fix guide or IRQL_NOT_LESS_OR_EQUAL Fix, which share similar troubleshooting approaches.

Step-by-Step Fix

Step 1 - Check Your RAM Modules

Since this BSOD often arises from faulty memory:

1. Press Win + R, type mdsched.exe, and hit Enter.
2. Choose Restart now and check for problems.
3. Windows will scan your RAM for errors.

If errors are found, reseat the RAM sticks or replace faulty modules. For advanced users, using a memory stress testing method like MemTest86 helps identify intermittent RAM failures.

If memory errors are confirmed, you may also experience MEMORY_MANAGEMENT blue screen issues. Follow our full guide here: MEMORY_MANAGEMENT BSOD fix guide.

💡 Pro Tip: RAM timing misconfiguration, especially when using XMP profiles, can trigger this BSOD. Temporarily disabling XMP in BIOS can help identify if memory overclocking is the culprit.

Step 2 - Update Device Drivers

Outdated or corrupt drivers are common culprits:

• Graphics drivers (GPU timeout errors may appear similar to memory faults)
• Network adapters
• Storage controllers

To update drivers:

1. Open Device Manager
2. Expand the relevant category (e.g., Display adapters)
3. Right-click the device → Update driver → Search automatically for updates

If updating doesn’t help, performing a clean driver installation with DDU – Display Driver Uninstaller can eliminate conflicts.

Step 3 - Check for Disk Errors

Since nonpaged memory relies on disk integrity:

1. Open Command Prompt as administrator
2. Run:
   chkdsk C: /f /r
3. Restart if prompted

This fixes file system errors and bad sectors. Learn more from Microsoft’s CHKDSK documentation.

Step 4 - System File Integrity Check

Repair corrupted system files:

1. Open Command Prompt as administrator
2. Run:
   sfc /scannow
3. Then run DISM:
   DISM /Online /Cleanup-Image /RestoreHealth

Official reference: Microsoft SFC & DISM Guide

Step 5 - Identify Problematic Drivers

Check Event Viewer:

1. Press Win + X → Event Viewer → Windows Logs → System
2. Look for errors marked BugCheck or PAGE_FAULT_IN_NONPAGED_AREA

Update, rollback, or disable the faulty driver as needed.

Step 6 - Check Startup Programs and Utilities

Clean boot to isolate conflicts:

1. Press Win + R, type msconfig → Enter
2. Services tab → Hide all Microsoft services → Disable all
3. Startup tab → Task Manager → disable nonessential startup items
4. Restart Windows

Step 7 - Advanced: Adjust Virtual Memory

Windows uses virtual memory as RAM extension:

1. Open System Properties → Advanced → Performance Settings → Advanced → Virtual Memory
2. Either let Windows manage or set manually:
   Initial: 1.5 × RAM
   Maximum: 3 × RAM
3. Restart

Step 8 - System Restore or Reset

If BSOD persists:

• System Restore: Win + R → rstrui → select a restore point
• Windows Reset: Keep personal files, reset system

Preventive Tips

• Run memory stress testing periodically using tools like MemTest86
• Keep drivers updated via official manufacturer sources
• Monitor overall system stability using a structured troubleshooting checklist
• Avoid aggressive RAM overclocking unless stability-tested
• Check disks regularly to prevent file system corruption
