Solution #3: Disconnect all external peripherals

If you have connected an external peripheral to your computer, then it could possibly trigger the occurrence of the Event ID 161. There could be a communication issue between your system and your device.

To fix this, unplug or disconnect all external peripherals, including the SSD, Bluetooth, and headset. And then, restart your computer and check if it resolves the Event ID 161 issue.

If the error is gone, then you have successfully resolved the problem. Otherwise, connect the external peripherals one at a time and restart your computer every time until you find the faulty device.

Solution #4: Switch off the Link State Power Management utility

The System File Checker utility is an in-built tool that identifies and repairs any corrupted system file on your Windows 10/11 computer. So, if a damaged system file is causing Windows to crash or the Event ID 161 error to show, then perform an SFC scan to fix it. Here’s how:
