VIA,
Avoid tips on here unless you golf well enough to understand what's cause your problem. Instead of fixes, I'll tell you what I think the problems are.
Slice with driver means clubface is open at impact relative to direction of clubhead travel. If club's square to line, yet club is moving left, voila - slice. Directly right on irons could be several things, from hitting on the extreme toe, inside out swing (which I doubt given the slice on the driver) or quasi shank (hit on extreme heel). You'll get far more out of someone watching you (even with limited knowledge) than you will listening to a bunch of guessers on this board.
