The kernel data inpage error is a Windows error code displayed on a blue screen. When this error occurs, your computer will typically compile some diagnostic data and then reset. If the problem persists, your computer will eventually crash again with the same kernel data inpage error message.

Kernel data inpage errors are usually associated with hardware failures related to memory modules and hard drives. In other cases, this same error will appear due to the effects of a virus.

How the Kernel Data Inpage Error Appears

When this error occurs, you'll usually see a message like one of these:

Your PC ran into a problem and needs to restart. We're just collecting some error info, and we'll restart for you.

Causes of the Kernel Data Inpage Errors

The kernel data inpage error is a stop code displayed during blue screen crashes, and is usually caused by a problem with the random access memory (RAM) or hard drive.

Here are some additional codes associated with this error, and the specific problems they refer to:

  • 0x0000007A: File access errors 
  • 0xC000009C: Bad hard drive sectors 
  • 0xC000009D: Loose cables or hard disk failure 
  • 0xC000016A: Bad hard drive sectors 
  • 0xC0000185: Unseated or damaged cables

How to Fix a Kernel Data Inpage Error

Since most kernel data inpage errors are caused by bad memory modules or hard drives, the fix usually involves locating the malfunctioning component and replacing it.

Computers that experience this problem usually boot normally after crashing. If your computer won't even turn on, or boot up, after experiencing a kernel data inpage error, check out our guide to fixing a computer that won't turn on.

In other cases, you'll find that a memory module or hard drive isn't properly connected, or the entire problem was caused by a virus. Here are the steps you should take to fix your kernal data inpage error:

Back up your data. If it's a problem with your hard drive, you could end up losing important data. If you have anything stored on your computer you don't want to lose, you should immediately perform a backup before you start the diagnostic process. At the bare minimum, make copies of any files you can't afford to lose, and store them on a USB drive or SD card.

  1. Inspect and reseat your memory modules if necessary. In some circumstances, this problem can be caused by improperly seated memory modules. To rule this out, and prevent an unnecessary expenses, open your computer and inspect your RAM. If any of the modules aren't properly installed, or have come loose, reseat them, then check to see if the kernel data inpage error still occurs.

    Exercise caution whenever you open a computer and physically touch components. Without a properly set up anti-static bracelet, static electricity may permanently damage components like RAM.

  2. Inspect and reseat your hard drive cables if necessary. This error usually indicates that the drive has physical defects like bad sectors. In some cases, you may experience this problem due to an improperly seated hard drive cable.

    To rule this possibility out, open your computer, locate your hard drive, and reseat the connector cable. You'll also need to check and reseat the cable where it connects to your motherboard.

    When your computer is running, listen carefully to see if you can hear loud clicking noises whenever your hard drive is running. If you hear noises like these, your hard drive may be in the process of failing, which can cause this type of error. The fix is to back up all of your data and replace your hard drive.

  3. Test your memory. Windows 10 has a built-in memory diagnostic tool, and there are also a number of free options available for Windows 7, Windows 8, and Windows 10. If you have Windows 10, type "memory" into the taskbar search field, then select Windows Memory Diagnostic > Restart now and check for problems.

    The best free memory diagnostic tool is MemTest 86. We highly recommend you download it and use it to check your RAM.

    You may want to run more than one memory diagnostic tool. If any of these tools report a problem with your memory, consider replacing your RAM. Doing so will probably fix your kernel data inpage error, but your RAM is likely to fail in the future either way if one of these tools finds a problem.

  4. Test your hard drive. You can check for problems with your hard drive using the built-in Windows error checking tool, or run chkdsk.

    If your diagnostic tool of choice finds any problems, like bad sectors, allow it to attempt a fix. If successful, you should be able to use your computer without any further kernel data inpage error crashes.

  5. Unplug hardware peripherals. While less likely, this error can occur due to other peripherals. To rule this out, you should shut your computer down, unplug all of your hardware peripherals, and turn your computer on.

    If your computer doesn't crash with the kernel data inpage error, reconnect each device one at a time. When you find the device that's causing the problem, you can either leave it unplugged or replace it.

  6. Run a virus scan. In some cases, a virus may corrupt important files and cause a kernel data inpage error. This is less likely than other possibilities, but it's still important to check. If nothing else has worked, try running a virus scan. If any of these programs locates a virus, allow it to fix the problem, then check to see if you're still experiencing kernel data inpage errors.

We maintain a large list of free antivirus software you can use to check for this type of problem.
