Why is my power supply making noise?

My computer is making a strange noise. I've inspected myself and have narrowed it down to my power supply. It makes this repetitive buzzing sound when my computer is on.

I can't explain. I thought it was overworked so I turned it off for a couple of days but it started again. Is it dying? Overworked? Do I have too many devices hooked up? If it's a simple matter of buying another power supply, please tell me. I just want the buzzing to stop.

If you are certain the power supply is the source of the noise, simply replace it Excellent power supplies can be purchased for about fifty dollars

Do a Google search to find a good deal, and be certain that your particular flavor of HP computer uses a standard supply Some PC's with non-standard supplies can be revived inexpensively by replacing both the supply and the case Call the manufacturer, if there is any doubt

Get the highest wattage rating you can afford I see by your profile you have a high number of peripherals, so I would recommend at least a 350 watt supply If the power supply is not already dead by the time you get this, it will be, soon.
