Oblivion: Bow and arrow glitch?

I've been playing Oblivion recently and in the beginning when you do the tutorial for the bow and arrows, whenever I pull the bow back, the arrow goes instantly then stops at the end of the bow, when I release it goes crazy and ends up mere inches away from me, this continues for the rest of the game on most characters no matter what race I choose. I have a character (Level 30 marksman) that uses bows and arrows, and whenever I use him, I can use the bow and arrows without any trouble. I know this game is old and whatnot, but I'm seriously getting frustrated that I can't make a new archer/marksman character.
