Really low tee shots with my driver

[Higgins1991]

I know asking for any advice may be a long shot considering I don't have a swing video yet but hopefully I can make it to the golf club tomorrow and take a few. Anyway, basically for the last 2 months any time I hit a tee shot with my driver the ball barely gets five feet off the ground and therefore goes about 30-40 yards in front of the tee box. I've been playing golf for two years now and never had this problem as consistent as it is just now (it happens on every tee shot!) and before this started happening I had gotten to the stage where my drives weren't necessarily long but they were straight-ish and high.

The sound at impact sounds as if I'm making a semi-decent connection but I'm obviously not, I'm just adding this information incase this gives any further indication as to what my problems are.

My irons are generally good, I can get those up in the air no problem. I have tried putting the ball further towards the inside of my left foot (I'm right handed) but to no avail. It's getting to the stage that I have completely no confidence walking up to the tee and it's really frustrating as it seemed the just start during one round and I can't seem to shake it.

Once again, sorry for the lack of a video of my swing, I shall post one as soon as I have it which will hopefully be tomorrow, but any suggestions at all based on the description would be greatly appreciated!

Thanks, John.

Make sure that your hands are not in front of the ball as it would be with an iron. line your hands up with the club head.
