Caps Lock Button Stuck, Weird Symbols When Typing

Caps Lock Button light stays on and when typing it ends up being weird symbols instead of letters. My daughter just bought this computer second hand so we don't have any more history than that. We brought up the keyboard viewer and it is set to US but the viewer keys are in symbols instead of letters on the screen keyboard and a number of those keys don't work don't light up on the viewer when pressed on the computer keyboard.

Please help! Thanks so much.
