My laptop recently started frezing up. It first started when I used Facebook-today it froze up with Itunes on-while a cartoon was being played. I use 1TB external as a backup & where I keep most of my items to save space on my laptop to prevent it from being bogged down. I'm taking a class for IT Security so I'm trying to learn things myself-no clue why this is happening. When it freezes I can not even get into task manager to shut anything down I have to manually press the power button to completely shut it off which I don't like doing-I'd rather (at minim.) be able to hit restart....help :) Teach me lol. Thanks
