What you want to learn about computers

First, I want to learn about how to attach youtube’s movies on powerpoint because I tried to attach them many times, but I could not even save the movies. Also, I asked some of my friends, but no one knew that. If I knew how to do that, I think my presentation would be more interesting. So, when I saw Mr. Poza’s blog and found that he attached youtube’s movies, I really wanted to know how to do that. Second, I want to learn about computer’s speed because my computer works very slowly at beginning, but it becomes normal speed after five to ten minutes. My computer is old, but I use windows XP, so I want to know why. It makes me annoy when I am hurry. Therefore, I want to learn about attaching movies and computer’s speed.
