Hello guys, 4 days ago I had a power outage where the electricity came back in a second and then off again in another second. Then 2 days ago, same thing happened. Now my PC makes a high pitched whining sound. When I shut down the pc, it makes the pitch go in a song like pattern, like it's making a song with the whining where the pitch goes up and down. Does anybody know what component to replace?
I have a motherboard: Asus H87 plus PSU: Seasonic 850 watt GPU: Gigabyte 660 CPU: i5 4570 Case: Haf 922
Any help would be appreciated, thanks!

More aboutmaking high pitched whining sound
It sounds like possible coil whine from the PSU. Do you have another working PSU you can use to test with?
only 2 components can have coil whine: 1) GPU 2) PSU
from what you described, im leaning towards the psu.
