How to Fix a 'KERNEL_DATA_INPAGE_ERROR' on Windows?

If you get a "KERNEL_DATA_INPAGE_ERROR" on Windows, try these steps: 1. Run chkdsk /f /r to fix disk errors. 2. Test RAM with Windows Memory Diagnostic. 3. Update or roll back storage drivers. 4. Disable Fast Startup and manually configure the paging file. 5. Run DISM and SFC to repair system files and image corruption.

If you encounter a "KERNEL_DATA_INPAGE_ERROR" on Windows, it typically indicates that the system failed to read required kernel data from the paging file or disk. This error often points to storage, memory, or driver issues. Here are several distinct approaches to resolve it:

The operating environment of this tutorial: Dell XPS 13, Windows 11.

1. Run CHKDSK to Scan for Disk Errors

This method checks the integrity of the file system and fixes logical file system errors on the drive where Windows is installed. Corrupted sectors or bad clusters can prevent proper reading of kernel data, triggering the error.

• Right-click the Start button and select Windows Terminal (Admin).
• Type chkdsk C: /f /r and press Enter. Replace C: if Windows is installed on another drive letter.
• If prompted that the volume cannot be locked, type Y to schedule the scan at the next restart.
• Restart your computer to begin the scan.

2. Test Your RAM with Windows Memory Diagnostic

Faulty or unstable RAM can cause the system to misread or fail to load kernel data from memory-mapped pages. This tool performs an in-depth hardware-level check without requiring third-party software.

• Search for Windows Memory Diagnostic in the Start menu and open it.
• Select Restart now and check for problems.
• Allow the system to reboot and run the test automatically—this may take several minutes.
• After completion, Windows will boot normally and display results in the Event Viewer under System logs → MemoryDiagnostic.

3. Update or Roll Back Storage Drivers

Outdated, corrupted, or incompatible storage drivers—especially for SATA, NVMe, or RAID controllers—can interrupt kernel-level data retrieval from the pagefile or hibernation file. Updating ensures compatibility; rolling back addresses regression introduced by recent updates.

• Press Win X and choose Device Manager.
• Expand Storage controllers and Disk drives.
• Right-click each relevant device (e.g., Standard NVM Express Controller) and select Update driver → Search automatically for drivers.
• If the error began after a recent update, right-click the same device, choose Properties → Driver tab → Roll Back Driver, then confirm.

4. Disable Fast Startup and Adjust Paging File Settings

Fast Startup can interfere with clean shutdown/restart sequences, leading to inconsistent pagefile states. Manually configuring the paging file prevents automatic misallocation and forces Windows to use verified disk space for kernel data swapping.

• Open Control Panel → Power Options → Choose what the power buttons do.
• Click Change settings that are currently unavailable, then uncheck Turn on fast startup and save changes.
• Search for Advanced system settings, go to Performance → Settings → Advanced → Virtual memory → Change.
• Uncheck Automatically manage paging file size for all drives, select your Windows drive, choose Custom size, set Initial size to 1.5 × your RAM and Maximum size to 3 × your RAM (in MB), then click Set and OK.

5. Scan for Malware and System File Corruption

Malicious code or damaged system binaries—including ntoskrnl.exe, hal.dll, or pagefile.sys—can corrupt kernel data loading routines. Built-in tools perform layered validation: DISM repairs the Windows image foundation, while SFC restores protected system files.

• Launch Windows Terminal (Admin).
• Run DISM /Online /Cleanup-Image /RestoreHealth and wait for completion.
• Then execute sfc /scannow. Do not interrupt this process.
• Reboot after both commands report success or indicate no integrity violations were found.
