Heh, what happens when you turn on the heater the first time of the year. It smells like burning!

Really... I'm not sure. You make have gotten some dust in there that is burning. It sounds like it has already run its course...

I would get a RMA from Dell. There systems only work with Dell PSUs, so you cant just stick in an Antec or something.

the new dells dont have propriatery psu and mobos...

as for the topic, you probalby just blew some dust onto or around the transformer.

Keep an eye on it if you see a flame or smoke. unplug it.

the dust will eventually burn.

edit: Maybe your just thinking too hard?

Hi Storm22,

I've had the same thing happen to me. That's why now I use a vacuum cleaner to clean out the dust first, then blow the dust out into the vacuum nozzle (while it's running!) to clear out everything I can. Those dust bunnies do stink, but I never had any real fires.

BTW - you mentioned that the PSU was a 250W Dell stock item. Some of those type power supplies are NOT standard in size. Dell, HP, Compaq, Gateway and others save monies on their PC's by giving you the least in the area of power.

I hope this helped, :)

Hi PatricKGG,

Nope! But allow me to re-phrase. The initial post was on the psu. Using the plastic end of a vacuum cleaner on the air vent of the psu, might suck out some of the dust particals. After an initial sweep over the psu, use a can of Blow-off or similar product and blow into the psu with vacuum end 6-8" from the opposite. Any dust being blown off will be sucked up into the vacuum cleaner and not spread around on the other components or you. I also use a small battery powered vacuum designed for this task, which I did not mention and I apologize for this oversite. I was in a hurry...

Always do any cleaning of a computer with it off and unplugged. Never jab or stab objects into the case for fear of loosening connections or breaking off capacitors and such. I've also used the swiffer dust wipes on the larger areas at the bottom of the case, case sides, fan blades, etc. Always ground yourself before poking around in a computer case. There is static in there as well. If you have a static band or other device, you should use it.

As for the article. It was interesting, but I personally don't disconnect any of the internal cables, connectors or such when cleaning. To much of a chance breaking something and making your pride and joy or someone else's a hugh paper weight.
The article did state using a battery powered vacuum was Ok:
< "It is safe to use a plastic nozzle of the vacuum cleaner to suck up dirt, dust, food, and hair from keyboards and the outside of the case. Never use an electric vacuum cleaner on the inside of the computer case. Electric vacuum cleaners create static electricity that can damage the internal components.
Battery powered handheld vacuum cleaners should not touch internal components. Getting too close can accidentally loosen cable connections, or remove jumpers from computer cards and the motherboard.">

I hope this helped explain a few thing, :)
