Hi @chinie05069225 I provide some simple steps to try to fix it: (1) Clean the keyboard: Dust and debris can cause keys to stick. Turn off your computer, unplug the keyboard, and clean it with compressed air or a soft brush. (2) Check for stuck keys: Gently press all the keys to make sure none are stuck or pressed down. (3) Use an online keyboard checker: Test your keyboard using an online keyboard checker tool to see if the keys are malfunctioning. This can help you identify if specific keys are continuously being pressed without your input. (4) Restart your computer: Sometimes a simple restart can fix the issue. (5) Test with another keyboard: If you have another keyboard, plug it in to see if the problem persists. This will help you determine if the issue is with the keyboard or the computer. (6) Update or reinstall keyboard drivers: Go to the Device Manager on your computer, find your keyboard, and update or reinstall the drivers.
