Troubleshooting Peripheral Devices

Correct Answer: Check the connection between the hard drive and the computer

The first step in troubleshooting an external hard drive that is not recognized by the computer is to check the physical connection between the hard drive and the computer. This includes making sure the USB cable is securely plugged in on both ends and trying a different USB port if available. If the connection is loose or faulty, the computer may not detect the hard drive. Formatting the drive, replacing it, or reinstalling the operating system are not appropriate initial troubleshooting steps, as they are more drastic measures that could potentially lead to data loss and should only be considered after simpler solutions have been exhausted.

Correct Answer: Loose or damaged video cable

The most likely reason for a computer monitor displaying distorted colors is a loose or damaged video cable. If the video cable connecting the monitor to the computer is not securely plugged in or has any physical damage, it can cause distorted colors or other display issues. A problem with the graphics card, while possible, would more likely result in more severe display problems or a complete lack of display output. A faulty monitor is also a possibility, but should be considered after ruling out a cable issue, as it is a more costly issue. Incorrect monitor calibration settings could cause color accuracy issues, but would not typically result in severely distorted colors.

Correct Answer: Check if the mouse is properly connected to the computer

The best answer is to check if the mouse is properly connected to the computer. If the mouse is not connected correctly, it will not work. The other answers are incorrect because even if the computer is turned on, if the mouse is not connected properly, it will still be unresponsive. Changing mouse speed settings or updating drivers will not resolve the issue if the mouse is not physically connected correctly.
