fender stratocaster road worn

Help with tuning a fender stratocaster?
i just bought a new road worn strat. and i cant figure out how to tune it with the tremolo. it was in standard when i got it but i tried tuning down half a step and they all screwed up. everytime i tune one string, another gets out of tune. i know the strings have to be balanced with the springs, but how exactly do i do that??
