Default High pitch noise from computer?

I am getting a really high pitched continuous noise from my computer every time the key is on. Is my computer about to fail? I was having a voltage code on it before and I took the alt to get tested and it tested fine. I am really worried that the computer is about to fry. Does anyone else have a noise from their computer? It can hear it from 10 ft away from the car so it is not a little noise.

it means your pizza is done... seriously, it may be that there's a short on one of the outputs. I've seen switching power supplies squeal when they were overloaded or about to fail. there may be no such thing in your computer, but it sounds like it might be about to eat the biscuits. maybe get a spare to carry if you can afford it?

One or more capacitors has gone bad and it's oscillating. Get another.

If you are absolutely sure the noise is coming from the computer, it is not long for this world. Replace it.

I have no problem with sourcing a salvage yard computer; I've had very good luck with them and the price is sure right compared to other options.
