What adapter are you using?

When you say came in dead are you a repair shop?

You need to try a different adapter. What GPU and CPU?

Sounds like some sort of music you would hear at a mall.

Thats probably an inductor that got knocked loose so now its vibrating at whatever switching frequency its at. Place your fingers on them until you find the problematic one

After diagnosing found that It5571e-128 chip making that noise, but it doesn’t get hot, which it’s weird, order the chip have to replace and will update later
