This has started happening a in the last few days and I don't understand why! One by one, the various windows open, most often Chrome, will start to lock up. I can open things like Skype and Steam, but once the window opens, it then freezes as well and can't be closed. If I put the cursor over the taskbar, it turns to the blue circle. If I leave it for long enough, the screen sometimes goes black but I can still see the mouse over it. Once it starts, I can't ctrl + alt + delete or anything, I have to hit the restart button.
