I'm having a couple of problems with my desktop PC running Windows 10, and I'm hoping someone here can help me to solve them.
Firstly, a white rectangle keeps popping up out of the blue in the middle of my screen and I cannot remove it. This rectangle shows the display settings; it shows above every window and every icon, and the mouse cursor goes under it when I move the mouse. I've taken a photo of the problem, which I hereby attach. This seriously interferes with the good functioning of the computer, because I cannot access anything under the rectangle while it shows. Any idea how I can get it to stop showing?
Secondly, the mouse cursor keeps getting stuck. I regularly have occurrences where there is no response when I move the mouse. I can always solve this problem by unplugging the mouse from the tower and then plugging it back in, but it is annoying to have to do that all the time. Any idea how I can stop this problem from happening?
Thanks in advance for your help.
