Step-by-Step Guide to Fixing the “PAGE_FAULT_IN_NONPAGED_AREA” Error

Dealing with the “PAGE_FAULT_IN_NONPAGED_AREA” error can be complex if you don’t understand what causes it. In this guide, I’ll walk you through the step-by-step process to identify, troubleshoot, and solve this pesky Blue Screen of Death (BSOD) error.

1. Understand the “PAGE_FAULT_IN_NONPAGED_AREA” Error

Explanation:
The “PAGE_FAULT_IN_NONPAGED_AREA” error occurs when the Windows operating system tries to access a part of your computer’s physical memory (RAM) that it believes should always be accessible but suddenly isn’t. This often points to either a memory management issue or a problem with the software/drivers interacting with memory.

Common causes include:

Faulty RAM or hardware.
Corrupted or outdated drivers.
Storage (hard disk or SSD) issues.

2. Software and Driver Check

Most of the time, this error is fixed by simply updating drivers or removing outdated software that could be interfering. It is worth noting that driver conflicts are a frequent trigger.

Update All Installed Drivers:
- Automatically with tools such as DriverFix or manually via Device Manager.
- Focus on audio, display, and network drivers as they’re common culprits.

Press Windows + X.
Select Device Manager.
Right-click on each driver and select Update Driver → Choose Search automatically….

3. Diagnostic Tests on RAM & Storage

Memory diagnostics and Storage checks are essential steps for every professional tackling this BSOD.

Memory Test:

Memory Test: Use Memtest86+ to analyze your RAM. Alternatively, if you want an easier, automated solution, try EaseUS OS2Go to create bootable diagnostic tools
- Download the tool and follow the instructions for creating a bootable USB.
- Run multiple passes (ideally 4-6) for thorough analysis.
- If errors are detected, consider testing one stick of RAM at a time or swapping slots to isolate the issue.

Hard Disk Diagnostic:

Use Chkdsk (Windows built-in tool) to check for any failures in your hard disk. Corrupt or bad sectors on your primary drive can result in Page Fault errors.
1. Press Windows + R → Type cmd → Press Enter.
2. In the Command Prompt, enter:
```
chkdsk /f /r
```
- This process can take a while if errors are extensive.

4. Update Your Motherboard/Chipset Drivers

Many forget that motherboard drivers are essential, especially chipset or memory controller drivers when you’re dealing with memory-related BSODs.

Navigate to your motherboard manufacturer’s website (e.g., ASUS, Gigabyte, MSI).
Download and install any available updates. A widely updated chipset driver can resolve memory address conflicts leading to a page fault.

Pro Tip: Updating BIOS/UEFI (carefully) can also resolve hardware communication issues, although it’s a more advanced step.

5. Run System File & Windows Memory Diagnostics

When memory isn’t the problem, corrupt system files or operating systems can be at fault.

System File Checker (SFC Scan):

Run SFC to scan for any damaged Windows files.
1. Windows + X → Open Command Prompt or PowerShell with administrative privileges.
2. Type:
```
sfc /scannow
```

Windows Memory Diagnostic:

Press Windows + R → Write mdsched.exe → Press Enter.
Choose Restart now and check for problems.
Let Windows automatically scan the RAM for errors.

6. Troubleshooting Drivers by .sys Files

If the error message includes a specific .sys file, this often points to which driver caused the issue. For instance:

For ati.sys, you need to reinstall/update your graphics driver.
Use the driver’s official website or tools such as NVIDIA GeForce Experience or Radeon Software for AMD.

7. Boot into Safe Mode to Fix Persistent Errors

Safe Mode allows you to troubleshoot without interference from problematic drivers or third-party software. If the faulty drivers or software can’t be disabled due to recurring crashes:

Boot into Safe Mode:
- Hold Shift → Select Restart → Select Troubleshoot → Advanced Options → Startup Settings → Click Enable Safe Mode with Networking.
Once in Safe Mode…:
- Update Windows and drivers without risk of crashes interfering.

Key Replacement Step: Faulty RAM

By this stage, if Memtest86+ is identifying errors the best solution is to replace faulty RAM sticks. Consider:

Switching the RAM locations in their slots to rule out issues with the motherboard.
Replace faulty RAM modules. Aim to use compatible RAM sizes and specs with your motherboard for best results.

Pro Advice: Stick to high-quality RAM brands like Corsair, Kingston, or G.Skill known for their reliability.

Frequently Asked Questions

1. What is the most common cause of “PAGE_FAULT_IN_NONPAGED_AREA” errors?

The error is commonly caused by issues with memory (RAM) or problematic drivers—especially those dealing with graphics or storage. Corrupt system files can also be responsible.

2. Is Memtest86+ sufficient to diagnose the error?

Yes, Memtest86+ is an excellent tool for detecting memory issues. You should run at least four full passes to get an accurate assessment of your RAM.

3. What should I do if Windows stop booting altogether due to this error?

You should try to boot into Safe Mode. Once there, update drivers, uninstall faulty updates, or revert to a System Restore Point before the issue arose.

4. How do I quickly check if a specific driver is responsible for the error?

The BSOD often lists a .sys file. If you find one related to this error, it’s often helpful to update or reinstall the driver related to it. You can manually delete the problematic driver using Safe Mode if updates fail to resolve the issue.
