Quote from: kregoron;376894I think most of the tips from others covers it.
Tho ive been asked frequently if its okay, to use a vacuum cleaner to clean the inside of a PC with. Not adviseable, the static electricity generated in the tube is enough to fry most bits ;) Just a friendly warning if anyone got that idea :)

I'm just using the nozzle to collect the dust I blow out with the air-can, I guess that's ok as I don't touch any components with it, and the PC is off.

I use a toner vac that has rubber hoses so no static problems :)

Unlike a photo pack for lighting, which runs at 4800 watts, unlike a good guitar amp...you'd really need to create a static chrage. Rule one..Unplug unit..then discharge by turning unit on/ off..this will disapate the charge...

The static they are talking about happens when dust and elec mix..I remember getting a lift on a concrete floor with a Fender Amp from a discharge...get a wrist band called a ground strap..it's an urban myth that a vacuum will kill a computer...but it might kill you, you are the ground.

Rubber won't conduct...er..enough dust gathered will send the charge...I myself don't use dusty items..lets here from some guitar players using Hi Wat.

Use wood..it's not true that wood cannot conduct electricity..sap is after all ember.

DUMP THE CHARGE, worst mistake anyone makes.

I can hammer a nail into a living tree and use it as an antenna, the Sap (ember) becomes my source.

Myself , I'd shut unit down, then hit power button, move unit to a safe place. Remove said video card and inspect. I smoke so i would have a q-tip with some elec cleaner..I would dismount the heat sink..then I would proceed to clean (By air) and carefully use q-tip to clean fan blades (Becareful) upsetting a single blade could cause noise and improper function.

After this is done, use a good Machine oil ( if yah notice theres a sticker on the back, go dead center), blow on fan to insure movement (your breath should be enough), should turn freely.

Re-install..

Then annoy people with can of air..lol

My father has an air compressor. I take my PC over there once a year and air-blast it.

That's a wet compressor, used in automotive, let me guess compressor and a vavle...you drain it after using..not advisable for electronics. Good for car parts

Well computer cleaned and much better than it was before.

Powered back up and all working well with nothing going pop except for an odd sound coming from one of the fans (not the CPU one or Graphics thank god) so as Atomant said might have got just slightly dislodged.

Powered off, little check and power back on, much less of a noise then 1 min later stopped completely so success. So if my machine makes an odd sound over the Lan weekend and your sat next / opposite me then it is likely the fan (hopefully) and nothing about to go bang.... Famous last words :blink:

Main point learned from the whole exercise is as Tut mentioned the can gets cold very quickly while using so short bursts and small clean/new brush used on out side plastics and internal plastics not connected to motherboard or other main units.

So......you've got a bite and here it comes.

I used to fix SMT stuff back in the day, I never wore an earth strap, I never took precautions and aside from the odd grab of a capacitor that hadn't discharged (and yes, it hurts), I never fried any components with static. I've built PC's, back in the day when nicked car stereo's and Reebok pump were all the rage, and never had an issue. I vacuum my PC, it's turned off, but I've never, ever had a problem and I really get stuck in with the hose.

Unless you are Captain Sparky, just dust blow it and suck up the expelled mess with a vacuum cleaner.

I've never worn a anti-static band, and never had a problem either. I've been building my own systems since they went to 586...so I'd probably be 7-8 when I actually started playing with parts obviously not paying thorough attention to electronics good practice.

The one time I've burned a component out before its time when building was when I put an over size CPU cooler on without enough clearance to my ram. As soon as I stood the computer up and tried to power it on. Something shorted.

TL: DR: I've never had problems with static, but have killed a computer with a direct short.

urban myth..

Right when the vacuum cleaner runs, a static charge is generated when the air and dust runs past the plastic tube, a charge as high as 600 - 800mv can be generated with ease.
modern motherboards is safeguarded up to around 200-300mv, so the risk is there alright..

From what I have seen over my life......Static damage is very person dependant.......I've worked with 3 people who we never let anywhere near anything static sensitive as they blew everything they touched if not fully strapped up and everything done absolutely by the book.......wasn't worth the hassle so we had the "normal" people fix anything sensitive and banished the static freaks to somewhere less sensitive.

Strangely one of them got a shock from a 5v fuse holder one night ...... When I touched it I could feel nothing......we got one of the other oddjobs over and he got a shock also.......we dismounted it and meggered it and compared to a new one and the holder was lower resistance than it should have been - so......if you can feel 5v then you are a freak of nature and shouldn't go near anything sensitive ;) .....if you're normal then just take the basic precautions and discharge yourself regularly to something earthed.
