So I was watching a movie on my Lenovo laptop and it started running slow, then it started to freeze up a bit so I tried to shut everything down but it took about 15 min to shut down so I had to force shut it down. I then tried to start it back up again but the loading screen was just black with a little white dash in the corner. I then did the procedure to hard boot it and it worked but it was extremely slow to reboot, it took about an hour and a half for me to properly shut it down. Does anyone know what it means??? Do i have a virus, I watch the movie online but it was a safe website that i use all the time. Does anyone else have this problem?????
