Really noisy PC

Well, pretty much anything with moving parts in it is going to vibrate to some extent. The problem is when the vibrations are allowed to get to such an amplitude that they're basically lifting/dropping your PC on the desk, making that noise.

Have you tried just putting something reasonably heavy on top of it, to hold it still?

you could also open your case and suck all the dust out, especially from the fans
and make sure all the screws are tight

Also, make sure your hard drives and CD/DVD drives are Really Well screwed in. Once my mounting screw fell out of dvd drive, and my pc vibrated so much stuff on top of it fell off

What is that language? Looks like Brainfuck but with () instead of []. Hmm.

Remove the shell and place the rest inside a box of bricks. Put on a lid of plaster or heavy wood on top. That should remove all noise.

Wise advice, my friend. Wise advice indeed. However somewhat impractical I feel! :)

take a piece of carpet and place your case on it.
use ducttape (sp?) and wrap it around every metal part that touches another metal part... this should stop it. if its a fan then use fans out of old psus to replace the damaged ones.
thats what i did to make my old pc more silent.
a silent psu helps, too... if you want to be sure then remove the fan and see if it vibrates but i think ducttape and carpet should work fine.
edit: if you dont want to mess with looking inside the psu then you could try to unscrew your psu and then see if the whole psu vibrates :/

the problem stems from our irrational instinct to support most objects with 4 contact points, whereas any engineer could tell you this isnt the best idea. the fundamentally best approach would be to cut off one of the supports, but in practice this is best solved by allowing a little elastic deformation, either by increasing the pressure (the abovementioned brick), or providing a less stiff medium which can deform (the abovementioned piece of carpet/rubber), so that all points make contact all the time, instead of providing a wobbly support.

for me, dust in one of the various fans in my main PC is usually what causes a high pitched noise (that or spiders who happened to wander into the fan when it was turned off ;o) I have the side off the case because one of the harddisks overheated (need to get round to buying a bigger case) so it's easier for dust to get in.

- get a can of compressed air from your local computer parts retailer - give each fan a blast near its centre. That worked in getting rid of the noise for me.

- you can lubricate the fans (don't use WD40 tho)

- if your system fan is variable speed controlled by the case temperature, try putting it into one of the constant power lines instead so it turns at the same speed constantly.
