Anyone know how to fix this?

This shit is really starting to bother me and has been here for over a month now. On the left upper side of my computer screen there is a transparent square box that appears every minute or so and whenever it appears, you can't click on that area, you have to move your mouse off it and it appears a lot when I'm trying to double click and it just pops up then I have to move my mouse off, go back, and if it appears again...it takes me like 5 fucking minutes to open a folder because of this shit and it's really starting to piss me off. I opened my paint document and painted the entire file on the paint document to black and moved the paint document right over the area then multi-clicked until the box showed up and took a picture so you can see the transparent box more easily. Please tell me if you know how to fix this.

 

Strange... have you tried resetting/updating your graphics drivers?

 

I would back up what's important and re-install windows.
