i have used loads of times hoovers in computers and never had anything go round. Tend to keep it plugged in (earthed) and then get the hoover to it (not touching anything)

A vacuum won't normally remove the muck from between the heat sink fins and an air duster is easier and safer to use.

Thanks for your help guys, will give the vacuum thing a miss then.

Got 1 of those compressed air things (from maplin next day delivery, big thanks) and opened the computer......yeeek!!! it looked like the inside of my dyson.....15 minutes later after a deep clean, no more noise.

A big thanks to everyone that gave me advice.

Vacuum cleaners create a lot of static electricity, which can be harmful to sensitive electronic components. Buy yourself a can of compressed air e.g. here

How can something that creates alot of static pass it on when there is a PLASTIC end.......?? in some cases a couple of feet of plastic.....!!!

I think you'll find as long as its NOT metal you will be fine hoovering it out

Why do you think that a plastic end will help? Obviously something else that you need to learn about!

:rolleyes:

Static electricity refers to the accumulation of excess electric charge in a region with poor electrical conductivity e.g. an insulator i.e. plastic, such that the charge accumulation persists.

But the hoover is earthed.....the connector to the hoover is plastic.......with a length of plastic.....maybe connected to a plastic pipe (or metal) with even more plastic on the end......i think you'll find that much distance will stop any static

I have to say, I've cleaned out my computer innards with a hoover for the last 5 years without having had any trouble... but I've always felt dodgy about using the nylon-bristle brush attachment. I think that would pose significant static risk. Maybe I've just been lucky so far.

I clean my pcs with hoover with sucker with a small paint brush to clean dust out, I do keep the sucker a few inches away but I never once had any issues with static, I bene doing this for at least 10 years

I think if it did create static we would all be walking around with sticky up hair.....i'm sure the people that make hoovers have figured out how to get rid of static now

and like most people i also hoover out my computer and its been just fine

That's not how static charge accumulates and works. The plastic ends of a hose are not earthed and I don't think the vacuum cleaner manufacturers have figured out how to change the behaviour of electrostatic physics. The chance of it causing damage is low but it does accumulate charge until discharged but if it's discharged against electronic components in a pc then it depends on how much charge has accumulated in that time and the ESD rating of electronic components won't be high enough in many circumstances of above several kVs.
