The problem you are having could be caused by a couple of things.

This is a "basic" rundown of how I set up my guitars.

1. Tune your strings up to your usual tuning.

2. Lay the guitar on a flat surface, so that there is no pressure on the neck.

3. Use a straight-edge that is reliable (I use a carpenters square) and place it on the fretboard of the guitar, so that it rests on the first fret and the last fret.
Use a feelers guage (the tool used to check points, etc. on automobiles) and find the .010 guage. At the 8th fret of your guitar you should be able to just slide the guage between the fret-wire and the straight-edge.
If there is to much of a gap, then your truss-rod needs adjusted.
If there is not enough room for the guage to slip through, then your truss-rod needs adjusted.

4. Make sure that when you do this check; the straight-edge is not resting on the nut or a pick-up. (this would throw off your measurement)

***If you are not comfortable with the idea of adjusting the truss-rod yourself, then take it to someone qualified to do it. You could damage the neck if you turn the truss-rod to much at once!!!
If you decide to do it yourself, DON'T TURN IT MORE THAN A QUARTER TURN FOR EVERY HOUR!!! Turn it a quarter turn, and then let it set for a while. Then tune the guitar once again....., and check the measurement.
Sometimes it takes a while for the neck to adjust to the new setting. That's why you let it set for a while.***

5. Once the neck is set correctly, you can then adjust the action of your guitar to your personal tastes.

If once this is done....., and you still have uncontrollable fret-buzz......
then you may need to have the frets either shaved or replaced.

By the way. There is a tool for your particular truss-rod. Maybe one of your local music stores has one.

Anyway..........I hope that something here helps with the problem.
If not, I'd take the guitar in to a qualified repairman.

Hope ya get it fixed, and best of luck. :cool:
