The video bdbl presented makes a lot of good points. The driver setup is significantly different than setup for your other clubs. Especially these big head, long shaft, low loft monsters used today. Treat it as such whenever you line up with a driver.

One tell tale sign that something is amiss with your setup is if your shaft has a forward lean. The shaft should pretty much be straight up and down to even a very slight lean back when you set up. Your hands should not be in front of the clubhead. I think you rarely see someone set up to a driver properly who doesn't lean his torso a bit to the rear when taking his stance. You really have to reach down with the right hand to grip the club so if you don't lean straight back as you reach down with the right hand you probably are throwing the right shoulder out a bit as described in the video effectively opening your shoulders to the target. Make sure the ball is forward enough in your stance. When you line up with a driver next time have someone lay a club on the ground up against the tee perpedicular to the target line with the end of the shaft down between your legs. Many times people think they have the ball far enough forward but it is sometime hard to judge from the address position. You cannot line up properly to the ball if you don't have it forward enough in your stance.

Do some searches and look at a lot of vidoes about hitting the driver. You will see a lot of the same fundamentals being repeated. Learn the fundamentals and get the mind set that whenever you pull the driver out of the bag it is a unique club that has it's own set of rules.

Keep in mind, this is just and opinon from someone with an 18 handicap. It is just something that seems to work for me. I'm not great but I hit my driver a lot better than most of the people with whom I regularly play.
