My laptop has been operating slowly for a few weeks. I ran ccleaner and antivirus software and removed threats. This last week, it keep freezing up until yesterday when it completely froze. I was able to periodically close the open internet sites on Chrome and open documents on MS Word. I restarted it three or four times, but now I can't open internet or MS applications. When I try, there is a long wait time, the apps open, and then either stop responding or immediately just shut down. My screensaver, which is photos from my pictures still runs, and my email notifications still pop up every now and then through a messages app on my computer. But I can't do anything except for see the list of messages. I tried to run task manager after start up and there was nothing running.
