I’m not sure what’s going on, my computer is having these moments where it spams the letter “a” it goes on for a minute each time I’d say, one time spamming “a” and “z” but only once. It happens maybe every 5-15 minutes. I disabled my keyboard on my laptop and unplugged my usb keyboard, and it still did it. Any idea of what is happening or what I could do?
