I just recently started to play Skyrim, but I was cut short by a major issue. I can click on hardly anything. When trying to open the menu and options, I'm fine. I can click on anything in the options menu. But when it comes to doing simple things like creating a character, I can't get the slider to move so I can adjust what he looks like.

I'm playing on a PC, Windows 7 64-bit. All of my computer components are well within the necessary guidelines to operate the game well.

Why can't I click on anything?
