Where did these boxes on my files come from?

[Ash Collins]

recently my computer crashed, and the next time i booted up, every file,
folder, icon and shortcut now has a small tick box (check box) in the upper
left corner. it doesn't make a lot of difference, however it is annoying and
i dont know how to change it.

also, when i click on the start menu, the are that usually shows all my
recently used programmes is now a white blank box. whats happened? how do i
fix this?
