Keeping the inards dust free is vital on a pc. Especially if Fans get blocked.
A small paint brush and a thin nozzle end Vac to suck up the dust is ideal but you have to be "VERY CAREFUL" using the Vac inside hte pc. Suck up a jumper cap or knock a transitor could be a killer to the system.
You can get a can of Aire Spray and blow the dust out.
Main place apart from the bottom of the case having hair balls is the CPU area and memory down the edge if you happy with removing components it will make your job easier.
If the build up of dust in fans is compacted dust then replace the fans.
Also check the fans are spinning especially if theres one on the AGP Graphics Card also.
I could right a book but keep it simple. Get the dust out.
Any loose dangling cables tie up. Elastic Bands are a waste of time, get some geniune Cable Ties.
I have bought a specialist mini vacuum cleaner that runs on batteries (from my local PC shop) and even though it is not as powerful as using an ordinary vacuum cleaner I know that using this there is NO danger of sucking up mother board components! It works surprisingly well on sucking up the dust.
I like many other people have recommended the old vaccuum cleaner way. But the other day, it came to notice that this method may cause static problems. Makes you think what is right and what is wrong nowadays.
One suggestion that I would consider:Make sure that the suction or interior cleaning doe's not loosen any components, or tugs on any cables etc.Check before you re-assemble the case.
