It is also possible for passive components to fail which may appear to
be an IC failure. Had a resistor pack go bad in a printer port
circuit once. I wrote a simple VB program to toggle the outputs on
the printer port connector, found the bad signal, traced it out,
discovered the pull-up resistor pack had gone bad and stole an
identical resistor pack from another "old" mobo to fix the problem.
Probably not worth the time spent, but fun stuff to do when you have
the tools and skills.
