How to Fix the Page Fault in Nonpaged Area Error on Windows 10

Page Fault in Nonpaged Area (0x50) is Windows discovering that memory it counted on being there has vanished. The “nonpaged area” is memory that must stay in physical RAM — drivers reference it directly — so when a driver points at freed memory, bad RAM corrupts it, or disk errors damage the page file, the system halts.

The practical upshot: this is a driver, RAM, or disk problem, and the crash dump usually tells you which. That matters because the three suspects have completely different fixes — updating a driver takes five minutes, replacing RAM costs money, and rebuilding a page file is somewhere in between. Guessing wrong wastes time or money, so the first fix below is always identification.

Work the list below in order. For the Windows 11 version see Page Fault in Nonpaged Area in Windows 11 24H2 , and for post-update cases the after-update variant .

Why this happens

• Faulty driver referencing invalid memory. Graphics, network, and antivirus filter drivers are the classic triggers.
• Bad RAM. Faulty memory corrupts the nonpaged pool, producing random-looking crashes.
• Corrupted page file. Disk errors in the page file area cause faults that mimic RAM problems.
• Antivirus filter driver bugs. Kernel-level security filters mishandling memory operations.
• Failing SSD/HDD. Bad sectors where the page file or driver files live.
• Overclocked or mismatched memory. Unstable RAM timings corrupt kernel memory structures.

How to fix it

Work through these in order — identify first, then repair.

Fix 1: Read the crash dump for the named driver

The dump usually hands you the answer.

1. Confirm dumps are enabled: Win + R > sysdm.cpl > Advanced > Startup and Recovery Settings > Small memory dump.
2. After the next crash, open C:\Windows\Minidump and take the newest .dmp file.
3. Open it in WinDbg Preview (free from the Microsoft Store) and run !analyze -v.
4. The IMAGE_NAME line names the faulting module — a .sys file means driver, ntfs.sys suggests disk trouble, and varying names across dumps suggest RAM.
5. Target that component in the fixes below.

Fix 2: Update or roll back the named driver

Replace the driver the dump implicated. Don’t just update over the top — a full uninstall followed by a fresh install clears corrupted driver files that an in-place update would leave behind.

1. In Device Manager, find the device, right-click, and choose Update driver > Search automatically for drivers.
2. If crashes began after a driver update, use Properties > Driver tab > Roll Back Driver instead.
3. For a thorough replacement: Uninstall device (tick Attempt to remove the driver for this device), restart, then install the newest driver from the vendor — NVIDIA , AMD , or Intel .
4. Test with the workload that crashed before.

Fix 3: Update or temporarily remove third-party antivirus

Filter drivers are a leading cause of this specific stop code.

1. Check Settings > Apps for third-party antivirus and note when it last updated — correlate with when crashes began.
2. Update it to the newest version first; vendors fix filter bugs regularly.
3. If crashes persist, uninstall it temporarily. Windows Defender activates automatically and is a perfectly good interim.
4. Test for a few days. If crashes stop, reinstall only the latest version of the third-party product — or stay with Defender.

Fix 4: Run Windows Memory Diagnostic

Rule out bad RAM with a proper test. The quick standard pass misses intermittent faults, so use the extended mode — it takes longer but it’s the only result you can actually trust for this stop code.

1. Press Win + R, type mdsched.exe, press Enter.
2. Choose Restart now and check for problems.
3. Press F1 during the test, select Extended, and run at least 2 passes.
4. With two sticks installed, test each alone if errors appear.
5. Replace faulty RAM. Also check for mismatched sticks — different speeds or brands in the same laptop cause this error on their own.

Fix 5: Check the disk and rebuild the page file

Disk errors in the page file area are the sneaky third cause.

1. Open an admin PowerShell and run: chkdsk C: /f /r
2. Schedule it for restart if prompted, then reboot and let the full scan run.
3. Afterward, reset the page file: Win + R > sysdm.cpl > Advanced > Performance Settings > Advanced > Virtual memory > Change.
4. Uncheck Automatically manage, set No paging file, click Set, restart, then return and re-enable System managed size. This forces Windows to create a fresh, unfragmented page file.

Fix 6: Run SFC and DISM

Repair Windows-side memory management components.

1. Right-click Start > Windows PowerShell (Admin).
2. Run: sfc /scannow
3. Then: DISM /Online /Cleanup-Image /RestoreHealth
4. Restart and monitor for further crashes.

Fix 7: Disable Fast Startup and test wake behavior

For crashes tied to sleep/wake cycles.

1. Control Panel > Power Options > Choose what the power buttons do > Change settings that are currently unavailable.
2. Uncheck Turn on fast startup and save.
3. In Device Manager, open your network adapter’s Properties > Power Management and uncheck Allow the computer to turn off this device to save power as a test.
4. Test several sleep/wake cycles.

Fix 8: Reset RAM to stock speeds

Eliminate overclocking as a variable.

1. Enter BIOS/UEFI (F2 or Del at boot).
2. Disable XMP / DOCP profiles and any manual memory overclocks.
3. Save (F10) and test for several days.
4. Microsoft’s official blue screen troubleshooting is documented in its Windows support hub.

Closing

Page Fault in Nonpaged Area is a three-suspect crime — driver, RAM, or disk — and the crash dump usually identifies which one. Read the dump, fix the named component, and test the other two if crashes persist. Worked methodically, this error resolves without a reinstall; worked by guessing, it drags on for weeks while you replace parts that were never broken.
