Sr, I have a Windows 10 PC. Last month, I have connected an external PS2 keyboard to my laptop. My laptop was OK till then. But after I disconnecting the external keyboard, my laptop was automatically typing square brackets whenever I go to write something. The problem is not solved till now. I have reconneted the external keyboard but it didn't fix the problem. I have also scan my PC for viruses with an antivirus software, but the problem has not been solved. So , I am now using my on-screen keyboard, but the auto typing still ruins me. And one thing I noticed that whenever I restarts my computer, there is a beeping sound. I have also reset my PC and clean installed Windows 10, but the autotyping problem starts after some time, and also the beeping sound when I restart my computer. I have also uninstalled the keyboard drivers and reinstalled and updated them, but the problem is still there. So, please suggest me how can I fix this big problem?

    Hi Debarghya_Acharya_640

    I am Vijay, an Independent Advisor. I am here to work with you on this problem.

    Let's first rule out whether the keyboard hardware is an issue or not. Can you use Keyboard tester and press keys to see if the keys are working correctly or not? If keys work as intended, then problem is not the hardware of Keyboard.

    If no hardware issue - Please try these options one by one and check after each option.

    1. Run Keyboard Troubleshooter

    Type Troubleshoot in Windows Start Search box > Click Troubleshoot > Scroll down and click Keyboard > Run the troubleshooter > Follow onscreen directions

    1. Turn off filter keys in Ease of Access

    Windows Key+i > Click Ease of Access > Keyboard > Ensure Filter Keys is not checked
