How to Fix the Kernel Data Inpage Error in Windows 11

The Kernel Data Inpage Error is one of Windows 11’s more alarming Blue Screen of Death (BSOD) issues. It usually appears out of nowhere and forces your PC to reboot unexpectedly — often while you’re in the middle of something important. The error typically shows up with the stop code KERNEL_DATA_INPAGE_ERROR and can be triggered by anything from failing drives to RAM issues and corrupted system files.

If you’re here reading this guide, chances are your PC has already crashed with this BSOD, and you want to understand what’s going wrong and how to fix it quickly. The good news? While this error looks scary, it’s usually fixable once you identify the underlying cause.

In this in-depth guide, we’ll break down everything you need to know about Kernel Data Inpage Error, why it occurs, and all the effective troubleshooting methods that can help you resolve it on your Windows 11 PC. Let’s dive in!

What Causes the Kernel Data Inpage Error in Windows 11?

This BSOD typically means Windows attempted to read data from memory (RAM) or the page file, but the data was missing or corrupted. Below are the most common causes:

• Bad sectors on your hard drive / SSD
• Failing HDD/SSD
• Faulty RAM
• Loose or damaged SATA cables
• Corrupted system files
• Malware infection affecting memory
• Corrupted page file
• Outdated storage or chipset drivers
• Power interruptions
• Faulty motherboard or storage controller

Knowing the cause will help you choose the right fix — but even if you’re unsure, the steps below cover all scenarios.

Fix Kernel Data Inpage Error in Windows 11

Below are the most effective troubleshooting methods. Follow each one carefully and check if the error goes away.

1. Restart the PC and Check for Temporary Glitches

A quick restart can resolve short-lived memory or paging issues.

1. Click the Start menu.
2. Select Power.
3. Choose Restart.

If the BSOD doesn’t return, it may have been a minor one-time memory glitch.

2. Check Hard Drive Health with CHKDSK (Fix Bad Sectors)

Since this BSOD often points to disk corruption, CHKDSK is the first tool you should use.

1. Press Start, type cmd.
2. Right-click Command Prompt → Run as administrator.
3. Type:

chkdsk C: /f /r /x

4. Press Enter.

Windows may ask to scan on next reboot — type Y, then restart your PC.

What this does:

• /f fixes disk errors
• /r identifies bad sectors
• /x forces dismounting

If CHKDSK reports bad sectors, your drive could be failing — back up your data immediately.

3. Check RAM for Memory Errors (Windows Memory Diagnostic)

Faulty RAM is another major cause of Kernel Data Inpage errors.

1. Press Windows + R.
2. Type:

mdsched.exe

3. Press Enter.
4. Choose Restart now and check for problems.

Your system will reboot and test the RAM.
If errors appear, you likely need to replace your RAM stick(s).

4. Inspect and Reseat Hardware Cables

Loose SATA/PCIe cables can cause intermittent drive read errors.

Try this:

1. Shut down your PC.
2. Unplug it from the wall.
3. Open the side panel.
4. Carefully reseat:
   • SATA cables
   • Power connectors
   • SSD/HDD mounts
5. Close the panel and reboot.

This is especially important if you recently moved your PC.

5. Scan for Malware That Affects Memory & Storage

Some malware injects itself into memory or manipulates the page file.

1. Open Windows Security.
2. Go to Virus & threat protection.
3. Click Scan options.
4. Choose Full scan.
5. Run the scan.

If malware is detected, remove it and restart your PC.

6. Update Storage, Chipset, and SATA Drivers

A mismatched or outdated storage driver can cause kernel-level errors.

1. Right-click Start → Device Manager.
2. Expand Storage controllers.
3. Right-click each controller → Update driver.
4. Do the same under:
   • IDE ATA/ATAPI controllers
   • Disk drives
   • System devices (chipset entries)

Restart your PC after updating drivers.

7. Run SFC and DISM to Repair System Files

Corrupted system files can lead to memory paging errors.

Run SFC:

1. Open Command Prompt (Admin).
2. Type:

sfc /scannow

3. Press Enter.

Run DISM:

When SFC finishes, run:

DISM /Online /Cleanup-Image /RestoreHealth

Restart your PC after the scans.

8. Disable, Rebuild, or Reset the Page File

A corrupted page file can directly cause Kernel Data Inpage errors.

1. Open Settings.
2. Go to System → About.
3. Click Advanced system settings.
4. Under Performance, click Settings.
5. Go to the Advanced tab.
6. Under Virtual memory, click Change.
7. Uncheck Automatically manage paging file size.
8. Select your system drive → Choose No paging file.
9. Click Set, then restart.

After restarting, rebuild it:

1. Return to the same menu.
2. Select System managed size.
3. Click Set, then restart.

This recreates the page file from scratch.

9. Test Your SSD/HDD with a SMART Health Tool

Use a third-party tool like CrystalDiskInfo to check deeper drive health data.

It reports:

• Reallocated sectors
• Pending sectors
• Read/write errors
• Drive temperature
• Overall health status

If the tool shows a Caution or Bad health status, your drive is failing — replace it immediately.

10. Disable Fast Startup

Fast Startup sometimes loads corrupt cached data into memory.

1. Open Control Panel.
2. Go to Power Options.
3. Click Choose what the power buttons do.
4. Click Change settings that are currently unavailable.
5. Uncheck Turn on fast startup.
6. Save changes and restart.

11. Update BIOS/UEFI Firmware

Old firmware may cause kernel-level read errors.

1. Visit your PC or motherboard manufacturer’s website.
2. Download the latest BIOS/UEFI update.
3. Follow their official instructions carefully.

Updating firmware can drastically improve system stability.

12. Completely Replace or Repair Faulty RAM or Hard Drive

If diagnostics show:

• Bad sectors
• Storage controller errors
• Failing SSD/HDD
• Memory errors

Then hardware replacement is the only solution.

Replace:

• The faulty RAM stick
• The failing SSD/HDD
• The problematic SATA cable

Backup your data immediately if a drive is failing.

Wrapping Up

The Kernel Data Inpage Error in Windows 11 can be intimidating, especially since it often causes your system to crash without warning. But as we covered in this guide, most causes come down to drive corruption, RAM issues, system file damage, or outdated drivers — all of which are fixable with the right approach.

By following the solutions above, you should be able to identify the culprit and restore full stability to your Windows 11 PC.
