I couldn’t imagine until now how a PC that has never been cleaned looks like. Fortunately, we can have a look. Just combine a lot of PC usage with no desire for cleaning and you’ll get the following result:

Judging from the look of those parts some of those pics are from relatively modern machines – I imagine it’s not just a matter of cleaning but of location. My dog sheds like crazy and my machine is located on the floor – even after 9-12 months it’s hardly dusty at all.

Methinks these machines were in a dusty basement corner next to a clothes dryer or something to have that much soot :-)

I can tell which ones came from a smoker. I had to do a similar ‘thermal repair’ on a heavy smoker’s PC. It was so thick, I was pulling strands of tobacco out from the heat sinks and fans. Totally gross.

Posted by Guy | May 4th, 2008 1:02 pm

@Mantari Damacy – It’s not tobacco. It’s a mix of nicotine and dust. I don’t know any smokers that dump tobacco into their boxes.

@mantari & Guy:The only thing in smoke that is sticky would be tar.

And it’s not that. These are just in a place with a lot of dust, maybe on the floor. It could have an intake fan that sucks all the dust..

Posted by Joe | May 4th, 2008 1:53 pm

Thats fairly common to see when working on computers. Many peoples PCs have that much dust in them. Smokers are the worst, you can tell by the brown colored dust. It’s all sticky and hard to clean out.

My very first PC in 1993 looked like this after a few years. It ran so good that I never thought of ever cleaning it. It’s only when things started going wonky that I had to open the case and realized just how much dust had been sucked inside.

I used to work in tech support and our company (paper distributor) had about 10 PCs in the warehouse. After a month sitting out there, a new one would look like the above pics.

Posted by someone | May 4th, 2008 5:01 pm

Weird. Coz I have a dirty apartment with lots of dust and a PC on the floor, but it doesn’t look anything like those pics… Those machines came out of the desert!

Posted by CH | May 4th, 2008 5:04 pm

I see computers like this all the time. Cleaning computers from smokers smells so bad, too.

Lesson: Clean out your computer every few months at least.

Posted by Jamesy | May 4th, 2008 5:17 pm

Wow, nice. I always keep my PC clean so it will run efficiently. As mentioned already location is important. A friend of mine had a computer beside a floor vent above a clay basement. Needless to say the computer was routinely dirty.

Posted by Guarl | May 4th, 2008 5:56 pm

Some PCs crash on hot days because of dust impeding the cooling fans. I wonder why PC makers don’t mount a particle filter, like in vacuum cleaners and cars….

Posted by Mark | May 4th, 2008 6:22 pm

Posted by dar7yl | May 4th, 2008 8:15 pm

I taped scotchbright (r) pads over the vents on my machine to cut down on the crap. It went from having to clean it once a month, to relatively crud free for the last 6 months.

btw – I’m a non smoker, but I have a wood stove that sometimes spews smoke into the room. (supposed to be air-tight, but you have to open the door to get wood in)

Hahaha, this is why i use filters on my fans. The filters are made with a really fine metal screen so they don’t restrict air movement much. I barely have any dust in my computer even after several years.

Posted by Michael Kean | May 5th, 2008 5:35 am

Laptops get like this too – but they’re easy to fix – just pick them up like a huge harmonica and blow into the air outlet. Be sure to wait a few seconds, or look away, before breathing in again!

Posted by Ron | May 5th, 2008 7:35 am

That reminds me of a computer I tried cleaning once. It was owned by a heavy smoker. I went at it with a can of air outdoors, in the dark, without realizing what I was up against. These are the pictures of it, _after_ the can of air:


Posted by Quitter | May 5th, 2008 12:04 pm

Eww that brings back memories. You can tell which are the smokers’ computers because of the brown color. I used to be a smoker until one day I was doing computer repair on a mobo completely layered with that brown funk. It made me feel so ill that I quit smoking tobacco!

Posted by Merc | May 5th, 2008 12:04 pm

Bad but not the worst I’ve seen. Went to check out a PC at local City Hall. Was an old IBM Z50 I think. Popped the cover off it, jaw came unhinged. The dust and lint was so impacted, I could literally pull it off, akin to cleaning a dryers lint filter after about 3 weeks of heavy use, it was easily an inch thick, and no parts of the computer could be seen. Been in warehouses and chicken houses that had cleaner PC’s. Amazed it was even working, not to mention the possibility of burning the place down. 25 years in the business and not seen another like it. City Hall.. it figures…

Ugh, must be a smoker’s machine. Definitely not the worst I’ve seen but not one of the best.
Every time I go to a house call and I walk into the clients home and smell the tobacco and smoke I shudder because I know that’s waiting for me in their machine..

Wanted to reply to something nik said: If it was a paper distributor, the dust was most likely from the paper. Environments like offices and libraries, and even hospitals (places that have lots of paper laying about) usually have a big janitorial staff. The reason for this is because most of the dust comes from paper (over 80%), and if it were left to accumulate, lets just say some folks allergies would go haywire in only a few days.

I used to live in a house full of smokers, and eventually picked up the habit myself after moving out (no surprise there)…

It always came to my mind to put some HEPA filters in front of the intakes…but I never did it.

Posted by Brian | June 5th, 2008 8:09 pm

I’ve had to repair one worse than this for my wife’s parents. They’re a really dirty couple, smoked asstons of cigarettes in their bedroom where the computer was. I found dust about 4 inches thick and cockroaches in it.

Long story short, I told them I refused to work on it and they were better off just throwing it away.

They put it back in their bedroom, where it collects dust to this day.

Posted by Bull3t | June 11th, 2008 9:41 pm

Posted by Choppy Lewis | July 28th, 2008 1:45 pm

Clearly this is at a minimum 3 diferent PCs, but I think it’s more like 5. The brown colored dust on the top 2 is not regular dust, it has a high iron content. You can tell because of the way that the dust has not only bee attracted to anything electrically charged in the computer, but how it’s aligned with the electric field around the capacitors. Although I can’t imagine where that dust would come from.

Posted by Ron | August 11th, 2008 8:02 pm

What is interesting to me is… You can tell the smokers from the non-smokers, by the ‘color’ of the dust! Which should be an affirmation to those that have yet to quit!

It was like someone stuffed the thing full of cotton balls. Guess they’re lucky they had a low-end sempron. I think it would’ve ran about 40 C without a heatsink

I dealt with donated computers and there are a couple that were worse than this. One was an old P1 machine that must have been around animals or something, as the front intake fan grille was matted with a mixture of what looked like dog hair and dust, at least a quarter inch thick. Another computer must have been in a machine shop or something, as it had an oily reddish-brown coating over all of its components – I originally thought the resistance coating was red!
