🛑 Introduction
I recently encountered the PAGE_FAULT_IN_NONPAGED_AREA
blue screen error on my system, and it was extremely frustrating.
The system would crash suddenly —
sometimes while browsing, sometimes during normal usage. Within a few minutes,
it would restart automatically.
In some cases, the system restarted
so quickly that I couldn’t even read the error message.
After testing multiple fixes step-by-step, I found the actual causes and solutions that work.
🔍 What is PAGE_FAULT_IN_NONPAGED_AREA Error?
This error occurs when Windows tries
to access memory that should always be available — but isn’t.
👉 In simple terms:
- “Nonpaged area” = memory that should never be
unavailable
- If Windows can’t access it → system crashes
This usually indicates:
- Memory (RAM) issues
- Faulty drivers
- Corrupted system files
👉 It’s a critical system-level error, not a normal
software issue.
## ⚠️ Why This Error Causes System Crash (IMPORTANT)
This error occurs in a critical part of system memory that Windows depends on.
When Windows tries to access invalid memory in this area, it cannot continue safely.
To prevent data corruption or system damage, Windows immediately stops and shows a blue screen.
⚠️
When Does This Error Occur?
You may see this error:
- After installing new RAM
- After updating drivers
- During gaming or heavy usage
- Randomly during normal usage
🧠
How to Identify the Real Cause (IMPORTANT)
Before trying fixes, identify the
likely cause:
- If crashes are random → likely RAM issue
- If started after driver update → driver issue
- If during heavy usage → memory stress or hardware issue
👉 Identifying this early saves time.

How to Fix PAGE_FAULT_IN_NONPAGED_AREA Error
Follow this order — don’t skip
steps.
## 🧾 Stop Code Information
This error is also shown as:
STOP Code: PAGE_FAULT_IN_NONPAGED_AREA (0x00000050)
👉 This code helps identify memory-related issues quickly.
✅
Method 1: Check RAM (MOST IMPORTANT)
This is the most common cause.
Steps:
- Press Windows + R
- Type:
mdsched.exe
- Restart and scan
Advanced
Check:
- Turn off PC
- Remove RAM sticks
- Clean and reseat
- Test one stick at a time
Why
this works:
Faulty RAM leads to invalid memory
access → system crash
✅
Method 2: Update or Rollback Drivers
Steps:
- Open Device Manager
- Update:
- Display drivers
- Network drivers
👉 If issue started after update → rollback driver
Why
this works:
Drivers operate at system level —
faulty drivers can cause memory access errors
✅
Method 3: Run System File Checker (SFC)
Steps:
- Open Command Prompt (Admin)
- Run:
sfc
/scannow
Why
this works:
Repairs corrupted system files
affecting memory handling
✅
Method 4: Check Disk Errors
Steps:
- Open Command Prompt (Admin)
- Run:
chkdsk
/f /r
Why
this works:
Disk errors can affect memory paging
and cause crashes
✅
Method 5: Disable Antivirus (Temporary Test)
Sometimes third-party antivirus can
cause conflicts.
👉 Temporarily disable it and check
✅
Method 6: Remove Recently Installed Software
If issue started recently:
- Uninstall new apps
- Remove recent updates
👉 Software conflicts can trigger this error
🔧 What Worked for Me (Real Case)
In my case, the issue started after
installing a new driver.
I tried:
- SFC → no issues
- Disk check → no issues
👉 The real problem was:
A faulty display driver
After rolling back the driver, the
crashes stopped completely.
⚠️
Common Mistakes to Avoid
- Ignoring RAM check
- Only trying software fixes
- Skipping driver rollback
- Not checking recent changes
📌 Final Thoughts
The PAGE_FAULT_IN_NONPAGED_AREA
error is usually caused by:
- Faulty RAM
- Driver issues
- System corruption
👉 Best approach:
Start with RAM → then drivers → then system repair
🚀 Final Tip
If the issue continues even after
all fixes:
It is most likely a hardware problem (RAM or motherboard)
