What's wrong with the computer?

My dad has been complaining about his Internet connection that he can't go other website except my sister's company website. Even my sister went over his place she also say the same. So tomorrow we are going over to see what's wrong with his computer.

I also find that my printer is using the cartridge fast, someone was telling me that if I didn't use the printer it should be turn off. If not the printer will keep on auto cleaning. Is that true?

Oh yeah I have been looking at the Digg and I don't know how to add the Digg button to blog. Anyone care to share how to do it?
