minecraft is not working correctly

minecraft is not working at all.
let me explain, i load up minecraft at the menu (in-game) but my mouse won't hover over the options because when your mouse hovers on options or single player 1 it does not light up and 2 i can't click on any options and it won't work. i have tried to uninstall it with the wizard i have tried just restarting it and and nothing happens. please fix this because now i can't play my favorite game anymore.
