The mouse is an essential tool for operating a computer. If the left click suddenly stops working, it can greatly impact productivity. Below are some common reasons for this issue and solutions to fix it. Let's dive in!

Method 1: Check the Mouse Hardware

Prolonged use can cause wear and tear or poor contact in the left button, which is a common hardware issue.

Replace the Mouse: Connect your mouse to another computer and see if the left click still doesn't work. If it remains unresponsive, the issue may lie with the hardware. Consider getting a new mouse.

Clean the Mouse Button: Open the mouse casing and check for dust or debris blocking the button. Use a cotton swab or a small brush to clean it thoroughly.

Method 2: Check the Mouse Connection

An unstable USB connection or wireless signal can also cause the left click to stop working.

Switch USB Ports: Plug your mouse into a different USB port to rule out any issues with the connection.

Check Batteries and Signal (Wireless Mouse): Ensure the batteries are fully charged, and there are no obstacles between the mouse and the receiver.

Method 3: Update the Mouse Driver

A corrupted or outdated mouse driver can lead to issues like a non-responsive left click. Here's how to fix it:

1. Download and install the "Driver Sentry" software, which can automatically detect missing or corrupted drivers and update them with one click.

5. Open Driver Sentry again to detect and reinstall the mouse driver.

Method 5: Check System Settings

Sometimes, accidental changes to the mouse settings can disable or swap the left click functionality.

Open the Control Panel, go to Hardware and Sound, and click on Mouse settings.

Under the Buttons tab, make sure the "Switch primary and secondary buttons" option is not enabled.

Adjust the button sensitivity to prevent the left click from being unresponsive due to low sensitivity.

By following these methods, you should be able to resolve the issue and restore your computer to normal use. To prevent similar problems in the future, consider using Driver Sentry regularly to check and update your drivers, keeping your system in optimal condition.
