5] Temporarily disconnect Accessories connected to device

Blue Screen Unexpected Kernel Mode Trap often occurs after the introduction of a new hardware component to the PC. This may be because of compatibility issues or even some sort of malware in the unit. To confirm when the problem is resulting from the same, simply try the following –

  • Safety disconnect or remove the hardware component(s).
  • Restart your Windows 10.
  • See if the issue persists.

If the blue screen still happens to come up, then hardware wasn’t the cause of it after all. Returning to the device you can reconnect them and attempt other fixes. BSOD error gone indicates that probably the hardware was the problem. In such a case, you can try the following two steps –

  • Thoroughly scan the device for malware with a reliable anti-virus tool.
  • Navigate to the website of the manufacturer company of the hardware. Find and follow their instructions to update driver of those devices.

They getting into your computer would mean a lot of trouble. This can cause the PC to hang, interfere with the smooth functioning of a system or can even delete important data of files without your permission. What’s more, the damages can even lead to blue screen errors.

  • Once the process is complete, the system will reboot on its own again.
  • After restarting, you can find the results of the scan in the Notification area.
