The UNEXPECTED_KERNEL_MODE_TRAP Blue Screen of Death can occur on any Windows iteration, but why does that happen in the first place?

A trap basically alters your OS mode by driving it to a kernel-based routine. Thus, instead of matching control with the executed process, the OS sets a higher priority on the execution of that process compared to user code.

What is Unexpected Kernel Mode Trap and what causes it?

As expected, bad drivers are the most common reason behind the UNEXPECTED_KERNEL_MODE_TRAP error, but there can be other factors that trigger the kernel’s failure such as:

• Faulty RAM modules
• Malware or virus infections
• Malfunctioning peripherals or hardware incompatibility
• Unsupported, outdated, or incompatible software plugins, or SSD firmware
• Poorly coded programs
• Corrupted system files or other data files that are damaged or broken

In other words, any files that fail the kernel’s integrity or compatibility checks can trigger the Unexpected Kernel Mode Trap on any iteration of Windows, including Windows 11.

In some cases, this error can be caused if your component connectors are covered in dust, so you’ll need to remove them and clean them properly before connecting them again.

How do you fix Unexpected Kernel Mode Trap error?
