Are they both diffident?

according to ohm's law it clearly states that current is directly proportional to PD ( when current increases ,PD too increases ) but in the other part the formulae P=V*I states that  current decreases when voltage is increased and vice versa....How is that possible ?? its like violating OHMs law....plz explain the difference if the above mentioned thing is correct ( of course correct coz text says so )
