My home computer (an HP desktop) wouldn't turn on after a power outtage in the neighborhood several weeks ago. The motherboard light was flashing, but still- nothing.
I figured I'd need to buy a new power supply and was loathing the idea of taking it in somewhere.
Anyway, I got totally bored earlier and opened my busted computer to check out the psu and did a major dusting inside, etc etc...
Was looking looking online for some parts, and found a site where people were talking about this method, and turns out...
Pointing a hairdryer into the psu fan turned the light solid green and everything powered up! I was amazed it actually worked, lol.
Anyone familiar with this?! Is it a temporary fix or am I good to go?! Everything is running smooth so far!

If it wasn't working and you blew out all the debris and now it's working yes it sounds like you're good to go, overheating will kill ya.
Most of us use a can of compressed air and a soft brush.
Preventative maintenance will stop stuff like you encountered...

I'd be careful about suggesting or using a brush on or near any circuit boards because they can quickly build up a static shock. Same thing for a vacuum cleaner, it should only be used on the outside of the case.
As far as the air goes I've been using the air from regular compressor. AFAIK the only difference is the compressed air in a can has lower moisture and won't have other possible contaminants like compressor oil. You can have a filter on a compressor, these are usually used on compressors used for painting. I just give it good long release of air to make sure the moisture that might have accumulated in the hose or elsewhere while it was sitting is gone.
I'll offer one little tip, if you have a noisy fan unplug it first and take it out. There will be a sticker on the center of one side of the fan blade, you can see it partially in the picture plwit posted above. Remove the sticker and discard it. Under the sticker might be a little rubber stopper, remove it if there is. Whether there is rubber stopper or not under that you'll see the shaft for the fan in the center. Take some regular oil like 3in1 and put one drop on it. I used the oil from my shaver one time as alternate. You could use any oil but something like wd-40 is hard to control the application and is really light oil so it won't last as long.
You computer will now sound like it was just bought.
While not sure what the correct name for the thing is, but a much cheaper device to blow dust out of fans and heat-sinks is what everyone with a baby knows as a "snot sucker".
Just don't use the same one on the kid and the PC.
Not nearly as dirty as the ones you have linked, but pretty filthy and plugged non-the-less. I can't seem to find the one where I found a frog in a client's computer. That was a strange day. It was a good sized frog too, maybe six or seven inches long, two inches at its widest point, squeezed its way through the fan-grill to get into a computer--and subsequently died.

That is all it takes !
When I was still working, our office had umpteen desktops, and we did notice that the ones on the floor were always the dirtiest.
So we made sure that they were located *off* the floor afterwards ...
They still get dusty regardless ...
Because of the *Static whatever* , the dust just collects there !
Shows you how much *crap* is in the air !!!
A bit off topic, but meant as a warning.
Ever take a look-see under your fridge ?
We have a *static* air-cleaner, and when we clean the filters and the static thingys, the water looks like coca-cola.
I am surprised on how good our body filters air.
I never had that dust problem, not even after years of running my old pc, which was also located on the floor. Modern towers have filters at the intake openings, so any air sucked in is pretty clean already. And when the ventilation system is designed correctly, the air is expelled or sucked out along with any dust particles that might have gotten into the case.
My main problem is humidity, metal parts in my computers tend to rust within a few years
