I used to blow the dust out of my systems with those air cans from Radio Shack, but I found they would also spit water and I stopped in a hurry..so they remain dusty..:(..--Phyllis

I have never heard of anyone having 'too much electricity'. The watch thing often has to do with body chemestry, not eletricity. And then only that the person get skin problems from the reaction between skin and metal. My wife has that problem. I have never heard of any electrical devices being damaged by a persons body chemestry or 'electricity'. When the computer is opened and the computer electroncs is touched by someone who has a stative build up on his body, that is not a result of the person's own body but from having built up static electricity because they did not discharge their body by touching a grouned object, like the computer case when the AC cord is plugged in [assuming that the ac outlet is properly grounded. You can use a ground fault tester to verify that it is OK. ] > They run for a while, and then die. Forgive me if I doubt that your mother's physiology is causing this. Were all of these dying computers in the same location when they died. There could be some electrical problem, like the faulty outlet mentioned above where they case does not get grounded because the ground prong [the round one] is not connected properly to the electrical system ground. This could happen in old buildings that have not been updated electrically, OR if someone replaced an damaged outlit and did not connect the ground wire correctly. [This would be a bare wire, not the white one or the black one. > Anyhow, early Wed morning I was merrily tooling along when the > motherboard fried.

As are damage from static electicity. This damage can happen with no apparent effect until later. That is why manufacturers require buiders of electronics to be grounded. Most electronics today has circuity to reduse the effect of static damage. So sometimes instead the eamage being immediatly apparent, the circuitry is only weakened, waiting for that inopprertune moment to finally fail. This kind of serupticious damage can be from bad mfg. practices or careless handling by repair personnel or the owner. > happy camper when the head technician showed me the blown capacitators. Capacitors used to fail frequently in the old days. Capacitors do not fail often today and when they do it is most likely due to excessive volatage applied, and possibly due to heat. > The dust inside of that box was horrible!

I like the idea of using a vacuum cleaner creavas tool, i.e plastic, not metal. Just be careful not to bang around. If the computer is in a dirty environment, i.e. dirt builds up, [this could be why your mothers 'puters fail]. Then a cleaning is a good idea, what? twice a year or something. > The upsides to all this is that now I have a new computer, improved > electrical connections in the outlet, a new UPS/surge protector, UPS is good, as are surge protection.

Yes, my knowledge base includes things learned from bad experiences, this in spite of having been both an electronics technian and a teacher of electronics.
