back to article Dirty PCs: How much filth can you take?

It's been a tad over a year since our shock insight into the darkest and most fearsome interiors of computing hardware, and by our reckoning that's just about enough time to recover from the trauma. Accordingly, we're inviting contributions for "Ventblockers II", so let's see if you lot can match this further collection of …

oh GOD, the smell!!!

This is all very interesting, and I've seen many at least equal, but it doesn't really convey the awfulness of opening a computer that has sat inches away from a heavy smoker for many years, the nauseating, nostril clogging stench. It also doesn't convey the disgust at the texture, its not just dust, its sticky, cloying, revolting. After having one of those in the workshop the stench lingers for days. What you need is smellovision and feelovision.

On the flipside

Yeah, I know what you mean. I've worked a few PCs that came out of smokers' homes. But a while ago a girlfriend gave me her old PC when she upgraded and besides getting a still decent computer I liked it because the scent of the perfume she always uses was coming out of the exhaust fans in back.

Re: Smoking and PCs

Many years ago when I was starting my PC support habit I had to fix an old PS/2 (the IBM type, not the Sony one) that had been on the desk of a heavy smoker. I took one look inside and refused to touch it - several inches of brownish tacky sludge covering everything inside the case. Even back in the early 90's it was agreed by all that this was a health hazard..

He ended up having a new PS/2. And smoking at the desks got banned shortly afterwards with the company setting up a cancer cabin for the addicts to go and smoke in.

Pah...

You should do desktop support at some of the fag manufacturers, the staff were allowed to smoke duty free tobacco at the desk so they smoked *lots* of it.

TVs too

colour CRT TVs this is; the ones that came from a smoking household and had been on 12 hours a day for a few years tended to grow sticky tendrils about the back of the tube and over the HT portions of the PCBs. A vacuum cleaner and brush would only ever be partially successful at removing it before you had to start working on it. Trike was the best stuff for getting it off.

No pictures, but I do have a story...

a number of years ago when I worked as a field technician for one of the local service companies, I had to go out to one of our client's rural offices- they had a workstation die and needed us to repair it.

I got out there, opened the case, managed to hold down my lunch from the stench of the mouse urine and droppings, and informed the client that it would have to go into the shop for decontamination and repair.

Fortunately, I had gloves with me and it got put in the back of my pickup truck for the ride back to the shop. I feel sorry for the poor sod who probably had to sterilize his workarea after dealing with the machine.

I agree

These machines were rather average compared to the "X-Rated" Pictures of last year. The Dells in particular. I find it humorous that PC makers put filters and such in their air intakes and the like, but neglect to mention to the end-user that they need to be cleaned... They should design cases more like the Antec 300, which leaves the filters rather obviously positioned just behind the front mesh, where it's rather easy to spot a pile of fur/dust/etc since it collects on the /outside/ of the case.

/Paris, because dirty computers aren't the only things that make one want to wear gloves.

This year, the fun and games in my neck of the woods down here in the Southern Iberian Peninsula, has been with Laptops!

I had several in, where I've had to strip them down to the gunnels and take the casings to the local garage to use their compressor to clean out exhausts! The dirt that came out! The CPU's started behaving a bit better with mean temperatures dropping 5 to 10º!!!

What people do with them I do not know????'

Word of warning ...

Don't use a standard air compressor, as found at a typical garage, when blowing out electrical gear. They typically don't have filters on them to remove water and oil ... Instead, for home use purchase a can of compressed dry air from a photo shop. For more industrial "bulk" dusting, purchase a small compressor with an oil filter & dryer on the output. And whatever you do, don't crank the PSI! Keep it down to "just enough" or you'll start loosening components ... I augment mine with a data-vac to remove the bulk of the dust, before using the compressor.

I usually give my laptop a good

Blowing out. I try to keep a can of compressed air on hand just to keep the fan coils clear.

It also helps if the machines are on the desk, or some intermediate ledge or shelf and in good airflow, rather than on the floor. On the floor or carpet, dust and fibers get circulated, and heat buildup just worsens things. I keep low-speed air blowers beneath or adjacent to my two laptops' ducts, but i stll blow them out every few weeks. Plus, i like to hear the fan go "ZZZWEEEEEEE!!!!!" I think i blow more air on the sound effects than on getting out the ghost turds (dust, in US Navy Sailor parlance, hehehe).

But, yeh, those rat and mud-laden machines are HIDEOUSLY DISGUSTING.

"Don't use a standard air compressor ... They typically don't have filters on them" - the one in the paint shop will.

"don't crank the PSI" - not a problem as long as you keep the blowgun at a sensible distance.

oh sweet jesus

compressors and canned air... dear god...

Industrial compressors. Nice. Nice as in nice oily air from it that is. just what you want...

And canned air. Ooh lovely very cold air, nothing quite like it to crack solder joints.

The other problems is that you;re BLOWING. that dust, where's it going? You don't know. Some of it you're jamming under components.

The whole point is to REMOVE it, not randomly shift it about. Use a vacuum cleaner. Either make sure the nozzle is grounded (static=BAD) or, some people use a paper funnel on the end. When you've got the loose stuff, use a WOODEN toothpick, it's hard and small enough to shift the crap, BUT not hard enough to cause damage to components. Then repeat with the vacuum cleaner.

BLOWING dust around randomly is just stupid.

Different standards...

Never, ever, believe a builder when they say they'll cover something up, "it'll be fine". Simply put, builders have an entirely different concept of the meaning of "clean". A inch thick coating of building dust over every surface translates as "clinically clean", piles of rubble and debris translates as "a bit of a wipe and it'll be clean"

I speak from repeated experience of building work in computing environments.

James Dore is a bit of a doughnut

I'm sorry but it doesn't matter how much sheeting the builder covers the machine in, the machine is still sucking air in from outside to cool itself. Therefore if there's dust in the air then it will get inside the machine, The only way to stop this is to stop the air going into the machine, in which case the machine will overheat.

Either encase the server and filter the air going into the case or move the damn server.

Anybody who can't work this out has no business looking after servers.

Thank you!

This was part of our risk assessment, which went roughly thus (I'm paraphrasing):

Either:

a) Encase and filter /entire 42u rack/ - Approx £2k, delay project start by two days

or

b) move server: requiring new, temporary, (exposed and vulnerable) fibre laid from current location to new location that's not under refurb or occupied (only suitable area was an unused bathroom, no mains power) Cost unconfirmed.

or

c) If firewall fails replace with spare unit in storage that has same image on it.

Guess which one we did.

Easiest (and cheapest solution)

Options a-c sound very familiar, I went also to c).

Moving fibres around technically can be done but usually costs so much you don't do it. Racks are even worse.

Disagree. It's in the way humans are made. Lazy bastards, the lot of us. Some of us have learned over time that routine maintenance is the easy way out.

Seriously?

I might have been in this game too long, but most of those PCs I wouldn't have even bothered taking pictures of!

Plus, the 486dx2 and the PIII should be excluded as they're clearly not in use.

I replaced a computer just last month and asked the customer whether they wanted the 8 legged inhabitant transferring to the new PC! They declined.

And I agree with the comment about laptops - they definitely seem to be the worst culprits these days. We regularly do before-and-after pictures in order to shame the customer into being more selective in where they use it!

Unfortunately no pictures, but a story.

About a decade ago I was working as a field tech for a Dell warranty service provider in Canada.

I got sent to a flower shop to find out why their machine was running so slowly and shutting down all the time.

Now, I'm used to dirty machines, but this one was worse than anything I'd seen or heard about.

I get to the shop and am shown into the back where they make the flower arrangements and do all the cuttings. The pc looks dusty from the outside, like everything else in the backroom, but nothing could prepare me for what was inside.

I removed the top cover on this first gen Pentium (you know, the cases where top and sides are one piece), and inside it was packed solid with dust. Not loose, floating dust, more like a dust brick that filled every inch of space in the machine.

I pulled it out in chunks. Cleaned it and replaced the fans. It's a miracle the thing would function!
