When my PSU failed with its "two state situation", I simply measured the
voltage.  Ideally, I would have put a 'scope across the power rails to see
if there was anything else wrong.  I suspect that there was*, but not many
people have a scope at home, so the voltage test is as good a test as there
is. 
 
*probably serious ripple leading to a lower RMS reading.
