Correct Answer: Check if the microphone is properly connected to a functional USB port

The best first step in troubleshooting a USB microphone that is not being detected by a computer is to check if the microphone is properly connected to a functional USB port. This is the most basic and essential step in diagnosing any hardware-related issue. Here's why this is the correct approach: 1. It's the simplest and quickest step to perform. 2. It addresses the most common cause of device detection issues. 3. It doesn't require any software changes or advanced troubleshooting. The other options, while potentially helpful, are not the best first steps: Updating audio drivers is a more advanced step and should only be considered after basic connection issues are ruled out. Adjusting microphone settings in the control panel assumes the device is already detected, which isn't the case in this scenario. Running the Windows audio troubleshooter is a later step in the troubleshooting process and should be done after confirming the physical connection is correct. By checking the physical connection first, you establish a solid foundation for further troubleshooting if needed, and you may resolve the issue immediately if it's just a loose or faulty connection.

Correct Answer: Check or replace the batteries in the keyboard

The best answer is to check or replace the batteries in the keyboard. Wireless keyboards typically run on batteries, and if the batteries are low or dead, the keyboard will not be able to connect to the computer. This is a simple and quick troubleshooting step that should be tried before moving on to more complex solutions. Moving the computer closer to the keyboard is unlikely to solve the issue, as wireless keyboards have a fairly long range. Reinstalling the operating system is an extreme measure that is not warranted for a keyboard connectivity issue. Purchasing a new wireless keyboard should only be considered if the current one is confirmed to be faulty after checking the batteries.

Correct Answer: Clean the optical sensor

Cleaning the optical sensor of the wired optical mouse can help to fix erratic pointer behavior, as dirt or dust on the sensor can cause irregular movements. Reinstalling the driver or updating the BIOS are unlikely to resolve the issue.
