Black Rectangles/Black Boxes All Over The Screen
When I turn on my computer, it's all fine until after I login. I get these patches of small black rectangles all over my screen which stay above windows and everything (see attatched photo). I located it down to being an issue with dwm.exe as the boxes go away when I end that task. I just don't know how I should go about repairing this issue. I have Windows 7 x64 Ultimate.
