Have you looked at Device Manager to see if there are any ! or ? there?
Since I installed 10, many windows will not open, example, PKR a poker game opens but when I try to go to a table all that comes up is a totally black window?
Also, many, many windows do not open, (blank page.) when on a window and they ask you to click here to do whatever, most of these just come up a blank white page.
