Well from the looks of it there is a lot of great content on your PC Quick Reference Guide.

Unfortunately I think you need to give your website more design. In my opinon old people like the basic look to websites like that, but it's really the younger people that are looking at computer information on the internet. Your design reminds me of boring history projects and searching for information on the internet...

I'm sorry if that offended you, but I think you could spruce some things up. Such as adding images of the parts of what your doing on the computer or other in the sections of your guide.
