PSU is making a buzzing noise and PC won't start

I had a power shortage and after that when I tried to turn on my PC and the PSU made a buzz like sound then the PC beeps but I can't see anything on my screen .is the PSU dead? Is something else wrong? Thank you

Replace the PSU. Sounds like the power surge killed it.
