Symptom: A QX-10 keeps shutting down, but at random and in an erratic way.
By erratic it will sometimes shutdown--Start---Shutdown--start---within a
1/2 second of each sequence.
It sounds like there is a short somewhere or at least some component
failing. But where? Its hard to diagnose because (1) It's intermittent
and (2) I don't want to run the machine when it's flip flopping on and off.
That's definitely not good for the components.
I've determined that it's either the PSU or mainboard at fault. Both are
for sale on e-Bay. However, I don't whant to buy both when only one is the
problem.
Any ideas how I might determine which? The PSU doesn't not fire at all if
there is no load on it.
