Please be careful when dusting off the interior of your computer. I mistakingly dusted out the inside of my machine with a mini electronic vacuum. The kind that is typically used to clean the dust under the keys of a keyboard or other electronics. Unfortunately, I ended up killing one of my sticks of RAM at the same time.

Oooh jeeze, yup that happens. Static electricity is not your friend if your a computer geek!

this is also coming from the kid who never uses a static wrist band...and wont til something actually gets zapped by me :mrgreen:

buy a cheap air can and blow out your fan and the power supply box that should help with the heat, if not buy a new fan

What I did was bang a little, not banging it with a big baseball bat (however I do feel the urge sometimes ) lol

I take my time when it comes to cleaning, a big dry cloth of kitchen paper and being careful that it doesn't stick. Lots of blowing from my lungs and I also use a small vacuum cleaner, however I don't use it on the interior, my chassis has a removable exterior with air holes in it and because the chassis is on a wooden floor without any kind of lifting from the ground its a working vacuum cleaner as it is. Its not something I'm proud of, but here we don't have the space to put it up, because it reaches the desk if it does.

Just get a new fan. They are not expensive.

Cranberry juice did the trick for me. Pour a little of it on the motherboard and it will clear it right up.

You shouldn't bang your computer at all. Just do as everyone here says, open the computer and clean it. Sometimes I use a vacuum cleaner very carefully to clean off all the dust.

You can buy a new fan - (just fan) on eBay auction,
Buy a good known brand
and attach it even with strips - it will be good to cool your CPU , VGA , case with no sound.
