sounds like you are hitting the ball with your weight on your back foot, along with hitting down on the ball too steep, and quite possibly swinging out to in which will slice the ball.

tee the ball up so you have 1/4 of the ball above the top of the driver at rest. place teh ball 2" behind your front foot. close the face of the club a fraction as you could also be hitting the ball with the clubface slightly open.

you have to rotate your shoulders on the backswing, and swing down feeling only your arms moving. the rest should fall into place. don't try and hit the ball too hard.

here are a few youtube video's for you to look over



hope these help.
