[NCLUG] Whistling computer

[Kirk Rheinlander]

Can you teach is some good tunes ?? ;-)

Do you have some freeze spray - it is available at most electronic stores, 
including Radio Shack.

When the thingy is whistling Dixie, spray the suspect board - (cold, -250F 
or so, out of the can!) is typically not detrimental to electronic 
components - they prefer running, colder is better - directly on the 
suspect components. The change in operational temperature should help you 
isolate the problematic component(s).

Disclaimer: Although this is a tried and true electronics troubleshooting 
technique, I have experienced hot chips physically blowing apart from the 
rapid change of temperature, so it would not be a recommended technique on 
expensive things like processors, unless this is a last resort (which is 
where it is typically used).
