Hi , Greg , the best way for me , take the computter out of the frame ,i take it away from the work area and use air on it first then i put it in an old oil drain pan , an use wd-40 on it with a baby bottle brush , spray the heck out of it , about every 3-4 hours , take turn shaft with vise grips and turn it till it frees , turn it about half way around and spray more 40 on it , work it and keep working it it will free up , when you have as lose as you need it hit it with the air agin to remove the excess wd , hope that helps you buddy good luck ,
