if(and(count(a1:a5)=0,count(b1:b5)=0,sum(c1:c5),"" )

(Note the "" is the ELSE clause of the IF statement, since you didn't
specify an ELSE requirement....)

This is also assuming that by a1:a5=0 you mean its count, and not its sum,
is 0. If it's sum you're referring to then replace count with sum in the
formula above.
