Filthy PC

  1. At first, I thought, "I've seen worse", then a bit later I thought, "um,
    maybe not."

    When I was in Morocco, I went into an internet cafe and thought I would
    catch a disease simply from touching the PC. The keyboard was covered in
    grease and filth and the mouse had a brown layer of dirt, apart from parts
    of the buttons where finger pressure kept them dirt free.

    My dream is a large airtight metal box, which I could place large items
    like this in, introduce a cyclonic movement of air to scrape the dust
    of, then drop the pressure to evacuate it all outside....

    Ah, sod that. Let's build that box bigger than this house - then I won't
    need to do the dusting :)

    That seems to be all fine dust, I tend to get furballs and spiders'
    nests. :)

  5. I recommend the Quentin Crisp approach to dusting :)

  6. The worst ones are the ones that belong to smokers. I took one in to
    fix for a friend recently. Didn't notice anything amiss while it was in
    the car, but when I got home and switched it on, the smell of the PSU
    exhaust air was vile. It lingered for days after I got the thing back
    to him; needless to say he got a very quick fix!

    Yes - dust will obligingly move from ones path, even when not requested so
    to do.

    I've had much worse. I've had fans so clogged they stopped moving, which
    the PC helpfully informed me of by crashing. Not to mention actual fluff
    balls.

    Have a look here for some horrors:

    I know the smokers PCs, the residue seems to glue in dust and hair inside
    the fan and heat unit, and I have had to repair loads which were simply
    solved by ungunking the fan with the solvent we used to clean dried out
    heatsink compound from chips...

  10. I've had nothing as bad as this, though I did buy 2 aerosol canisters
    from PC World for lesser dust/fluff problems. They were utter rubbish,
    although I may have reduced their effectiveness by using them upside
    down to freeze off a couple of skin-tags.

    I did like the apparent effectiveness of the compressor and air-line
    on the video though.
    Is an airbrush type compressor suitable for this kind of job?
    I wouldn't want to go overkill.
    Also, does there need to be a moisture trap somewhere along the line
    to prevent water and electricity mixing?

    Where I worked repairing laptops, they had a compressed air setup with a
    airline and trigger adaptor that used to give a very effective blast of air.

  12. Some posters on here don't recommend them because of a) the possibility
    of generating a static chargeat the air gun nozzle which could damage
    sensitive components, and b) the possibility of spinning fans so fast
    that they are damaged (or the back EMF damages their drive transistors.)

    All I can say is, it's never been a problem for me, and I've de-dusted
    probably hundreds of machines using an air gun connected to a compressor
    delivering 8 bar without issue, many of which have been in very low
    humidity conditions in hot and dry locations.
    Should be fine.
    Ideally, you want dry, oil-free air.

    Yes and it's all a great bit of fun until some nugget discovers that
    Compaq screws are a reasonably loose fit in the tube.

    8 BAR + steel bits = Dunno, I can't see any more, but I suspect
    holes in PCBs...

    12-bar I know about; is this as a response to the current air of austerity?
