The PAGE_FAULT_IN_NONPAGED_AREA (Stop Code: 0x00000050) is a common Blue Screen of Death (BSOD) error on Windows 11. It typically occurs when the system requests data that isn't found in the memory, often due to faulty RAM, outdated drivers, or disk file system corruption. This guide provides a step-by-step approach to diagnosing and fixing the issue.

Step 1: Run the Windows Memory Diagnostic Tool

Because this error is frequently caused by physical memory issues, you should first check if your RAM modules are functioning correctly.

• Press Win + R, type mdsched.exe, and hit Enter.
• Select 'Restart now and check for problems'. Your PC will reboot into a diagnostic environment.
• Once finished, Windows will restart. You can view the results in the Event Viewer under Windows Logs > System.

Step 2: Check for Disk Errors with CHKDSK

Corrupted sectors on your Hard Drive or SSD can trigger memory paging errors. Using the Check Disk utility can repair these logical errors.

• Open the Start menu, search for Command Prompt, and select Run as Administrator.
• Type the command chkdsk C: /f /r and press Enter.
• If prompted to schedule the scan for the next restart, type Y and reboot your computer.

Step 3: Update Your Graphics and Chipset Drivers

Incompatible or outdated drivers are a leading cause of BSODs in Windows 11. Focus specifically on your GPU and Motherboard drivers.

• Right-click the Start button and select Device Manager.
• Expand Display adapters, right-click your graphics card, and select Update driver.
• Choose 'Search automatically for drivers'. Repeat this process for IDE ATA/ATAPI controllers and System devices (Chipset).

Step 4: Adjust Virtual Memory (Paging File) Settings

If the paging file itself is misconfigured, Windows may struggle to manage data transitions between RAM and the disk.

• Go to Settings > System > About and click Advanced system settings.
• Under the Advanced tab, click Settings in the Performance section.
• Navigate to the Advanced tab and click Change under Virtual Memory.
• Uncheck 'Automatically manage paging file size for all drives'.
• Select your C: drive, choose 'System managed size', click Set, and then OK.

Step 5: Disable Fast Startup

Fast Startup saves an image of loaded drivers to a hiberfile to speed up boot times, but it can sometimes reload a corrupted driver state that causes the Page Fault error.

• Open the Control Panel and go to Hardware and Sound > Power Options.
• Click 'Choose what the power buttons do'.
• Click 'Change settings that are currently unavailable' (requires admin rights).
• Uncheck 'Turn on fast startup (recommended)' and save your changes.

If the error persists after these steps, it is highly recommended to reseat your RAM sticks physically or test them one by one to rule out a hardware failure.

💡 Pro Tip: Keep your software updated to avoid these issues in the future.
