Noisy PC

I have a problem - my PC isn't working properly, he became too noisy and when I start to play games it begins to be even louder! What can I do with it, have you got such a problem?

If still noisy after that, come back here and tell us more about your problem. For me, it is often a fan which needs cleaning or lubrication - but since there are 3-5 fans it can be hard to tell which - I use the eraser end of a pencil to press on the hub of moving fans to see if the noise changes.
