cleaning computer..

maya

I know this is not much of a question for this group, but in
comp.sys.ibm.pc.hardware.misc there are hardly any articles, I didn't
think I would get a response there too soon..

I'm having a cable guy come this afternoon to install two digital-tv
tuner cards in my computer, but I noticed the slots where these cards go
are very dusty.. I have one of those compressed-gas dusters (thought
when I bought it yesterday that it was compressed air, not compressed
gas, don't know if this makes a difference..) I don't know if it's ok to
use it to clean inside the slots, I'm not saying open the computer, just
if it's ok to "blast" into the slots with the compressed-gas duster..

reason I'm asking is that in instructions to dust machine here,
http://www.velocitymicro.com/sysguide.php#dust
it says all this stuff about static electric discharge that I found a
bit scary.. it looks like it applies only to when you actually open the
computer, but am not not sure...

the guy's coming in about an hour or two, so would very much appreciate
a prompt response.. I need to know if I can "blast" with the
compressed-gas duster into the slots before he installs the digital TV
cards..

thank you very much....

That compressed gas if fine. I use it all the time and have never had a
problem.

I think it's an actual vacuum cleaner than can have "static" problems

I've used that cleaning method without issue.
I also use a Shop Vac with small attachments.

Just make sure you ground your machine to kill static, sprinkle some water
on your hands and chests (just to be on the safe side) and drop a few drops
of water on the floor. There is a lot of static in dry weather.

My house is wall to wall carpet...the most I've ever done is touch a
metal part of the case.
An occasional shower never hurts though ! :D

This is where your static appears: when you shuffle your feet on synthetic
carpet floor. It does not always happen but theoretically after taking a few
steps you can acquire enough charge to kill a chip. When I touch my cat in
the winter or even light switch I get hurt. My cat does not like it either.

Theoretically, lightning could strike me in the butt while cleaning my
PC ... I don't take any precautions against that happening though.

If you are walking around arcing off your cats...a grounding strap may
be necessary.

Then stop touching your cat, you moron. Jeez.

That appears to be another attribute of right wingers. Besides torturing
cats as youngsters, they also like to torture humans when they grow up.
BTW, don't mention "straps", it'll get them going even more.

Cheers.

As an extra bit of info, for a grounding strap to be effective you
must connect it to ground. This means either leaving the computer
plugged in and turned off in order to ground through the plug or
connect to some external grounded metal to bleed off the charge.
Connecting a ground strap to an unplugged computer case merely raises
the computer case to the same static voltage level as yourself and
indeed the isolated components are still in harms way since no charge
was able to be eliminated.

As an example, I can, and have, grabbed the hot wire (Black) in a
house while standing on a floor in rubber sneakers. Nothing happens.
It is only if some other part of you is touching ground, such as the
white and/or ground wire or in a bathtub where the water completes
the circuit to grounded drainage systems. No current path and no
transfer of charge works the same way with static and computers.

One last tidbit of info, IC's are much more immune to ESD when
soldered into a circuit but prudent caution is advised if you live in
a dry climate with shag carpet.

AlexB

It also depends on where you live.

Move up north to get more static. If you are in Tampa, lightning will do it
for you.

It is the other way around. My cat walks around arcing off me. Aside from
all the precaution I mentioned, I do have a ground strap on top of it or
rather under my hardware . Good luck with your "theoretical."

This is all very very true and displays an admirable understanding of basic
physics which is uncommon among our hs graduates who prefer cooking classes
to physics or math but then choose as a career writing "free" software.

I'm sure you still believe that water itself conducts electricity. It
does not.

What was said below is basic electricity, not necessarily physics. In HS
I majored in math and electronics, but never touched physics.

DanS, the fact that you did not take physics in you HS (and even proud of
it) clearly shows. Anyone who did, however, knows that you do not understand
what you are talking about. The PURE WATER, and I repeat, chemically pure
water is an isolator, with dipole molecules as they are and it does not
conduct electricity. We are not talking about a pure evaporate/condensate or
distilled water in here which requires special equipment. We are talking
about water with impurities which are purposely included in drinking water.
Have you, IDIOT, ever heard of chlorine? Its major part is chloride, an ion,
my dear and it changes the physical conductivity of water. In water it
breaks into Cl and H which is proton. This stuff is in every idiot's stomach
but they of course have no idea about it since they never took physics and
are proud of it.

Once you added chlorine to it the dielectric quality of water is gone,
disappears. The water with impurities becomes a low concentration solute and
all solutes of this sort DO CONDUCT ELECTRICITY. It does not take the
chlorine actually to kill an arrogant idiot. The water in any river or a
pond has many soluble cations and anions and they do conduct electricity.

I do not want you, as*ho*le to be hurt but if another idiot wets their hands
and touches a raw electric wire then the consequences may be tragic. This is
because even the purest water on your hands can kill you. You, idiot, may
think that you have a loophole in here, but in fact you don't. Even if you
wet your hands with the purest water in the world the next thing that is
going to happen: it becomes impure because you drop it on you idiotic hands
that never touched a physics textbook.

Your skin that perhaps was very dry with your epithelial level being a good
isolator because it is carotene instantly becomes a very good conductor and
it is because this purest water in the world that you paid a thousand bucks
a pint to do your idiotic experiment soaks the epithelial cells and they
exude (I do not expect you to know this word, of course, but hopefully you
can catch the meaning), yes they exude ions which are there aplenty. Those
ions include potassium, sodium, chloride, sulphate and others. And if any
idiot does it he is as good as dead. Period. Even if you believe that "water
does not conduct electricity," you, idiot who, throws his weight around
challenging people with education and knowledge will be dead as well.

What else shall I add to this lecture? It was very important, because you
are spreading medieval ignorance, my dear and it may cost people lives. You
are a dangerous man, an involuntary commitment might be an option for you.

The last thing I want to add that the static electricity behaves pretty much
the same way I described, So far I was talking about the power grid, etc.
But coulombs in low quantities do accumulate anywhere it there are favorable
conditions. These conditions are predicated on a very dry environment
because it saps water out of you and when you shuffle or rub your idiotic
feet you become electrified. And I do not mean in a good sense because you
cannot do anything "electrifying" even if you are charged with enough static
to kill and idiot. However, no idiot so far as far as I know has ever been
killed by the static because there is not enough of it, an idiot gets a sort
of an advanced warning and somehow discharges it. The best way to discharge
the static is to spray it with what, take a quiz you, idiot? Water, my dear,
water. Some commercial sources want you to believe that their special,
unique, patented solution does the trick much better than simple tap water.
It is pretty much the same when some characters around here are trying to
convince the unsuspected public that their APIs are better than native Vista
APIs.

Was it you idiot who tried to challenge me on the API internals yesterday?
If not you then another idiot must have been there. Or perhaps you have a
double,

The very last thing, For some it is not an issue or it is even a laughing
matter as another idiot indicated yesterday that he quoted that worn out
adage about an unlikely lightning that may strike his computer. If he goes
to Tampa, Fl the "unlikely" may well become "likely" since Tampa is the
World Capital of Lightning. The highest number of thunderstorms is
registered in Tampa area. I am sure that idiot has never been to Tampa or
even never saw a Tampanian in his life because if he did he would have
realized the healthy respect for mother nature is engraved on their faces.

If he is in Tampa and still do not believe me he should stand next to his
computer in a good thunderstorm and wait. No special equipment is necessary.
In no time and with no warning the event will arrive. He does not need to
check his chip if it is still alive. It is surely as good as dead. All he
need to do is to make sure his butt is not in Saratoga.

For people in Northern latitudes, you idiot, static electricity is a daily
and shall I say rather annoying reality. The cold dry weather saps water out
of you and even if you idiot run to your refrigerator to grab another beer
10 min later you are again high and dry.

The moral of the story is: do not take seriously what an idiot like DanS
tells you about static not being dangerous. It is. I won't kill you but if
you neglect physics which DanS refused to take in his HS because he could
not understand it anyway and I assume his math never went higher than
multiplication of numbers with 3 digital places.

Think about it: static can kill your precious motherboard or a video card or
anything with very delicate semiconductors. Again, DanS thinks I am talking
gibberish. I am sure he has never heard of semiconductors, he thinks
computers are made of clover leaves and potato chips.

They say curiosity kills the cat. No, ignorance kills idiots.
