The unexpected kernel trap error is a BSOD error is caused when the trap generated by the CPU was not caught by the kernel, so the computer freezes or shuts down. Below are some possible explanations for why this happens.

• Faulty Hardware: The most common cause for the unexpected kernel mode trap error is hardware failure. If the peripheral I/O devices are damaged or incompatible, they can cause faulty PCI and VGA cards. Sometimes, mismatched hardware memory can also lead to this error. Instances, when dust builds up and overheats your motherboard components can cause system crashes such as this one.
