I'd see if there was some way to put a voltmeter on the power coming in.
If the computer draws more than the supply can put out, the supply voltage
will drop.
I've never seen a resistor short- I've had several caps short out on me,
though. It's evident when that happens, though - there's usually a bang and
puff of smoke.
I'd expect the smoke if anything shorted out, the components usually aren't
rated highly enough to survive a dead short. Usually it's some passive that
goes, though.
Hi
I had a resistor short through its outer cover ( painted carbon film ) and
take
out a 90 volt line in a pinball machine display. It seemed to have been also
enhanced
but some old dust that was attracted to the 90 volt lines.
When in the military, I had carbon comp resistors reduce value by as much
as 50% but I've never seen one that wasn't run above its rated voltage
short from end to end.
1/4W resistors don't like 6KV and 1 amp supplies. The arc created might
count
as a short.
