Why Unexpected kernel mode trap occurs:

For this, you need to understand “what is Kernel Mode first”

To begin with, you should know that any computer works in 2 modes:

  • first is Kernel Mode, on which the operating system works, and,
  • the other one is User Mode, which can be accessed by the users like us.

To make it simpler to understand, just go through this example:

If you like to run a movie on your system, the video software (running on user mode) sends a “trap” signal to the hardware like display and sound card (which are accessed through only Kernel-mode) to make it happen for real.

So, if you relate to it correctly, the unexpected kernel mode trap will only occur in such a situation where the User Mode can’t access the Kernel Mode via its trap signals by all it means, Right?

This Unexpected kernel mode trap is also known as BLUE SCREEN OF DEATH (BSOD) as there is nothing you could do from here on but to read the instruction carefully on the Blue Screen and try to fix it after you restart the system, Again!

You need to carefully note the error message shown on the Blue Screen of Death, as that the way you can pinpoint what is exactly causing this error in your system.

These situations can occur in various cases, including any of the reasons from the below inexhaustive list.

  • If you have installed new hardware in the system.
  • If you have installed a new driver to make hardware work.
  • If you have a bad, corrupted, or outdated driver running on your system.

Now it is the right time when you know a little better about the error, we discuss how to fix it, Right?

But before we begin sharing a step by step procedure to resolve the issue, we recommend you to take a full backup of your data present on the system to an external hard drive, which can only happen when your system can restart without much trouble just after it showed you a Blue Screen Of Death.

It usually works when your system has shown this error for the very first time or once in a while every several months.

Otherwise, go for a full data recovery first with external help or connect your hard drive to another running computer and try to do it.

Now let us take you to some steps to follow.

To begin with, here is a way.

 Take Control of Your System From This Error Or BSOD!

  1. First and foremost: Check the memory – the error can be caused by faulty or mismatched memory. To do so, your system should be in a condition to boot normally or in safe mode.

Step 1: After booting your system > open windows search box > type memory diagnostics > choose restart now and check for problems > check the diagnostics report after the memory check is done, and your system is booted normally.

Step 2: Press Windows + R key on your keyboard to open Run box > type: “eventvwr” and press Enter key on your keyboard.

Step 3: Click on the System on the left side of the box > navigate to Filter Current Log from the right side of the box.

Step 4: In the even source box, click on MemoryDiagnostics-Results and Ok to see all the results.

Step 5: If the log shows errors, try doing suggested methods there, and if the log doesn’t show any error, continue below pointers.

  • The error could also come due to some hardware failure or incompatibility.

Wondering, what to do?

Start with removing the newly installed hardware and checking the system. If there is damaged hardware, try to replace it with a new one and check the system.

To identify which hardware has failed, follow these steps:

Step 1: Go to Start > Click on Settings

Step 2: Click on Update and Security > click on Troubleshoot

Step 3: On the right side of the pane, click on hardware and devices > click on Run the Troubleshooter.

C. To keep your system healthy and working fine all the time, you should always keep your system updated. Try doing that as the updates are made to make the system stable by fixing all the software and hardware issues.

To do Windows Update, you can follow these steps:

Step 1: Go to Start > Click on Settings

Step 2: Click on Update and Security > Click Check for Updates and install the required updates.

D. Check of Device Driver issues: If you have recently installed or updated any device driver, try removing it and check your system.

E. Maybe your system needs a firmware update. But you should only update the firmware of your system when your system’s hardware is compatible with it.

Try checking: Windows Compatible Product List before you proceed for a Firmware update.

Word of caution: We would recommend you to read everything you can get your hands on before you could attempt to do this, as this is a complicated step.

  • What does an unexpected kernel mode trap mean to a windows user like us?

In simple terms, your system’s Central Processing Unit (CPU) has generated a Trap that the kernel has miserably failed to catch. The Trap is a software-based interrupt, that is initiated from the Central Processing Unit (CPU) to other peripheral input-output devices to perform an action. Through these trap instructions, the software can access the hardware indirectly.

  • What causes kernel-mode heap corruption, and how can we tackle it on our own?

You must have seen a Hex code on your Blue Screen, definitely something like below:

UNEXPECTED_KERNEL_MODE_TRAP
  • 0x00000000 – represents Divide by Zero Error (Indicates that a DIV instruction is executed and the divisor is zero. Memory corruption, other hardware problems, or software failures can cause this error.)
  • 0x00000004 – represents Overflow (Occurs when the processor executes a call to an interrupt handler when the overflow (OF) flag is set.)
  • 0x00000005 – represents Bounds Check Fault (Indicates that the processor, while executing a BOUND instruction, finds that the operand exceeds the specified limits. A BOUND instruction ensures that a signed array index is within a certain range.)
  • 0x00000006 – represents Invalid Opcode
  • 0x00000008 – represents Double Fault, etc.

As you can see from the description with the error code from above, they represent an error due to hardware, firmware, or a driver failure.

Try correcting them from all the above-shared steps, and you will have your system working fine soon.

Conclusion:

After reading all the above shared tips and tricks, you should have all the right tools to fix your system by yourself. The unexpected kernel-mode trap is for sure a difficult thing to tackle, but it is just another resolvable error.

So, go ahead and follow the steps to reach a root cause and fix that and spread the word to help your friends.
