PAGE_FAULT_IN_NONPAGED_AREA Error: BSOD — Diagnosis and Resolution

What is the PAGE_FAULT_IN_NONPAGED_AREA Error

The PAGE_FAULT_IN_NONPAGED_AREA error (code 0x00000050) is a Blue Screen of Death (BSOD) that means the system tried to access data in memory that wasn't there.

This indicates:

• Faulty RAM
• Driver conflicts
• Hard drive issues
• Overheating components

Main Causes

1. Faulty RAM — one or more modules are defective.
2. Driver conflicts — outdated or corrupted software.
3. Hard drive problems — bad sectors.
4. Overheating — CPU or chipset overheating.
5. Weak power supply — unstable voltage.
6. Malware — malicious programs.
7. Overclocking — unstable settings.

How to Fix the PAGE_FAULT_IN_NONPAGED_AREA Error

1. Check Your RAM

Option A: MemTest86 (Recommended)

1. Download MemTest86
2. Create a bootable USB flash drive
3. Boot from the flash drive
4. Run for at least 4 passes

Option: Built-in Windows Tool

1. Open "Command Prompt" as administrator
2. Type: mdsched.exe
3. Select "Check for problems" → "Restart now and check"

Result: Memory errors → replace the RAM module.

2. Update Drivers

Update key drivers:

• Graphics card: NVIDIA / AMD / Intel
• Chipset: from your motherboard manufacturer's website
• Network: Realtek Ethernet

3. Check the Hard Drive

chkdsk C: /f /r

Restart your PC to run the check.

4. Roll Back the System

1. Press Win+R → type systempropertiesperformance
2. "System Restore" → "Launch"
3. Select a restore point before the error appeared

5. Check the Power Supply

• Ensure the PSU wattage is sufficient (minimum 500W for an office PC, 650W+ for a gaming PC)
• Connect all power cables
• Replace the PSU if necessary

6. Reset Overclocking

If you overclocked:

1. Enter BIOS
2. Reset settings to Default
3. Save and exit

7. Check Temperature

Use HWiNFO or Core Temp. If CPU is above 90°C — there's a cooling problem.

Prevention

• Use quality RAM modules with a warranty.
• Don't overclock components beyond stable values.
• Monitor system temperature.
• Update drivers to stable releases (not beta).
• Use an Uninterruptible Power Supply (UPS).
• Regularly clean your PC of dust.
