Here, we list some other common fixes for this error. You can try them one by one to remove the unexpected kernel mode trap. Overclocking can also cause unexpected kernel mode trap errors. If you overclocked the computer where the error occurred, you would need to disable the overclocking on this computer or restore the CPU to the default clock speed setting.
On the other hand, disabling memcache might also help with unexpected kernel mode trap errors.
To disable them, follow this short tutorial:
Step 1. During computer bootup, press the F2 or Del key to enter BIOS.
Step 2. Disable overclocking in step two.
- Go to the page for overclocking configuration. Overdrive or AI Tweaker are possible names for it. Pay close attention to the memory and CPU configurations. To remove Speed Step and set performance memory profiles to XMP, expand them.
- Alternately, go to the Exit page and choose Load Setup Defaults. The setup defaults are often set up to have overclocking disabled.
you should first search for the hardware in the Windows Compatibility List to verify that all hard drives, hard disk controllers, and SCSI adapters are compatible with the version of Windows you have installed.
If the hardware is compatible with your Windows, you should try updating the BIOS, SCSI controller, or network card. To update SCSI controllers and network cards, you need to use EaseUS DriverHandy to update the drivers under network adapters and storage controllers.

Hardware issues such as cracks, scratches, or defective components on the motherboard can also cause UNEXPECTED KERNEL MODE TRAP errors. If the above doesn't work, I think you should take your system board to a repair facility for a diagnosis.
Computers have two modes of operation: user mode and kernel mode. Operating systems typically run in kernel mode, which gives the operating system full access to all hardware and causes the machine to execute any instruction it has. An unexpected kernel mode trap typically means that the CPU generated a trap and the kernel didn't catch it, which can cause many problems. Fortunately, the editors of EaseUS provide you with eight effective solutions after research. You can help more users in need by sharing this article.
Unexpected Kernel Mode Trap FAQs
After reading this article, if you have other related questions, please continue reading this section. The following questions may be of concern to you:
1. What is an unexpected kernel mode trap?
"UNEXPECTED KERNEL MODE TRAP" is a Blue Screen of Death BSOD error that can cause your Windows to suddenly crash or freeze. The error described typically occurs whenever the CPU generates a trap or the kernel fails to catch an exception.
2. How can I get out of kernel mode?
User mode is a restricted mode that restricts software access to system resources, and kernel mode is a privileged mode that allows software/programs to perform privileged operations.
Hence, when a user-level application needs to perform an operation that requires kernel-mode access, such as accessing a hardware device, it must make a system call to the operating system kernel. Windows switches the processor from user mode to kernel mode to execute system calls and then switches back to user mode after the operation is completed.
3. What causes kernel crashes?
A kernel panic, also known in the Windows world as a stop fault or blue screen of death (BSOD), occurs when the operating system cannot determine how to fix a low-level error. The causes might be updated Windows versions, incompatibility, RAM errors, hardware errors, and more.
