My computer froze and a window popped up, titled "Microsoft Windows". It said that the application is not responding with the options to cancel or end process, but I couldn't click either because I couldn't click anything in the frozen state. This continues until either it unfreezes (which is sometimes followed by freezing again) or I turn the computer off. Any help would be appreciated.
EDIT: Just froze again, and all open windows or applications stopped responding. This time, I was able to click cancel on the "not responding" window. My changing wallpaper theme was still changing in the desktop, and I could move one window for a little while until it too stopped responding. After the freeze, the most recent window or application I was using is automatically closed. I have no idea how to fix this problem, please help!
