Try something like
NDSolve[{y''[t] == -y[t], y[0] == 1, y'[0] == 0}, y, {t, 0, 1},
StartingStepSize -> 1/10,
Method -> {"FixedStep", Method -> "ExplicitEuler"}]
For more details and to see what methods and other options may be
specified, see the tutorial
Advanced Numerical Differential Equation Solving in Mathematica
in the documentation. The above example is taken from there.
