But... once you get it open.. take a vacuum cleaner hose and suck all the bigger clumps of dust/lint etc out. If you have a soft bristle brush attachment that might be the next step. If not... and you have a soft bristle brush you can use to lightly brush everything and loosen up the dust that has become adhered to the motherboard etc then that would be good and then lightly vacuum it again.
There will probably be a fan mounted on top of your processor. Take that fan off and put the vacuum hose up to the fan frame. Sucking air through the fan will cause it to pick up some pretty good speed. Be careful... don't over do it but you DEFINITELY want all fans cleaned well (processor cooling fan & the power supply fan) and all surfaces that are directly being cooled by the fans. Any dust in the fan or on the surface being cooled will vastly reduce the cooling ability.
Just be as gentle and as thorough as you can. You don't want to break anything but you do want to get the whole system (especially portions that have to do with cooling the computer down) as clean as possible.
A computer (generally) isn't an overwhelmingly brittle device. You're not shutting down a nuclear weapon or anything... just be mindful that you don't put any undue stress on the machine as much as possible.
And.. btw... it isn't unintelligent to not know something... it is unintelligent to not ask.

I would NOT do that. First of all do NOT touch any parts inside. Second buy a can of compressed air. Open the case. Hold it so it is tilted over so the dust bunnies come out. Get the compressed air and blow all the dust out. Don't tilt the can because the liquid will come out.
If the fan is excessively clogged and the air is not blowing it out then you might try a dry q-tip or something.
Make sure no wires are also impeding the movement of the fans.
Then check the fan on the power supply and clean it as well. After you hear the beeping is there any lights on? Does it continue to beep? Also, next time your PC does not boot up to the log in screen after having to shut it down or something (without doing it properly), put the original OS CD in, if it's Win XP and go to the restore console. It will ask if you want to run it and should put you in an MS-DOS like mode. Run chkdsk...which has taken the place of scandisk. If often puts lost files back in their place.
look for loose wires and cables. When you turn the PC on and the fan starts up, after the beep does the fan stop?
What OS? What CPU?
Maybe the video card is bad. How old is the PC?
Again when you open the PC be grounded. An static and you can fry the PC...
Also if the Fan was not working before, you may have over heated the CPU and in that case it may be toast.
