Problems With Windows 10 Or My HP Laptop...Please Help

Tweet

I hope I am able to describe the problem I am having with my laptop to where it will make sense as it is very strange. I have an HP15 laptop and I am using Windows 10. First, let me start by saying that I have gone into settings and disabled the magnifier. I also disabled the touchpad while I am using the keyboard. Now the problem: whenever I am typing, my computer does some really strange stuff. Sometimes, while I am typing, it will automatically magnify my whole page. Sometimes, while I am typing, I get a white box that comes up ( as if I had right clicked). Other times, while I am typing, a small white box comes up at the top of my screen that has something to do with translation. I have tried looking on line for any fixes but can't come up with anything. All of this is happening while I am typing normally. I am not hitting any other keys besides letters. I try to be very careful and it still happens. It gets so frustrating as it's almost constantly happening. By the way, it happens on both Firefox and Chrome. Has anyone else had this problem before? Any help would be greatly appreciated as I am at my wits end.
