If you are lucky, the noise is coming from one of your cooling fans.

Open the case, and see if you can find what part the noise is coming from.

If it is a fan, shut the PC down, and try cleaning the dust off of the fan housing and blades.

Check for any hanging wires near the fan that might be hitting the blades.

If the fan itself makes the noise, it is best to replace the fan.
CAUTION: if the noise is from the power supply fan, you are safest to have a technician replace the fan. There are high voltages present even after unplugging the supply.

If the noise is coming from your hard drive, it is time to plan to replace the drive.

Back up your files NOW.
Purchase and install a new drive ASAP.

That means its happy:) No it could just be that your case screws are no longer tight. If they are loose it will cause a vibration. Put your hand on the case, do you still hear the sound? If not tighten all screws and hold downs. If that did not worklook inside at the fans and cdrom to see what is causing the humming.
