Please describe the noise and/or upload an audio sample.

To test if a fan is making noise, I place my finger on the center hub to
stop the fan.  (I then remove my finger after ~1 second and the fan
starts again.)

For power supplies, I typically shutdown the computer,open up the case,
disconnect all the load pigtails, unplug the computer from AC power,
place a known good power supply next to the case, connect its pigtails
to the load, connect its AC power, and power up.

To test for vibrating components, there are two approaches:

1.  Touch components with something that absorbs vibration and/or
increases mass (e.g. finger, pencil eraser, alligator clip, pliers, etc.).

2.  Use a mechanic's stethoscope, or substitute (a solid rod, microphone
and headphones), to determine what component is making the noise.
