Windows 7: Know any good computer related YouTube channels?

I enjoy watching hardware and software "stuff" on YouTube, but it's hard to find "good" stuff. Here are some users I like.....I also have some of my own stuff on YouTube under the same user name. (nate42nd) although you can't really call mine "good stuff" it's some of the first video I have ever shot and the best I can do with my Canon G9 is 1024 X 768.

Do you know any good ones besides these? These are all user manes on YouTube.
