Default High Pitch Whistle, No Power on System.

I am working on a computer that I can't figure out whats wrong. When I got the computer from the client it would not turn on. The only thing that would come on is the green power LED light on the front of the computer. It would not POST or anything. I tried different RAM too. The fan on the power supply wasn't spinning making me believe its a power supply issue. So, I took the PSU out and put in a different one. When I attempt to turn it on there is a god awful high pitch whistle. I assume its electricity? Very strange and never have came across anything like this. Does anyone know what it may be?
