DSolve[y''[x] == ay'[x] + y[x], y[x], x]

Try above. You missed the argument x.

I'm using Mathematica 5; DSolve[] never works. I am literally copying from
its own documentation, and it still spits out failures. For example:

In: DSolve[y''[x]==ay'[x]+y[x],y,x]
	DSolve::dvnoarg: The function y appears with no arguments
Out: DSolve[y''[x]==(ay)/x+y[x],y,x]
