Selam Everbody.

is it possible to fix this PCB of ST1000LM025?

PCB is short. it doesn't let the pc boot.
or shutting down PC immediately at work.

i desoldered the TVS diode but it's O.K. at separetly.

You can use either a USB or SATA PCB with same MCU (the square Marvell "M") and same motor chip (the rectangular Ti chip) and switch the ROM chip.

AFAICT, a short on the 5V supply could be due to the bridge IC, motor controller, or any of the MLCCs adjacent to these chips. Your last photo shows both capacitors and inductors. The inductors should be OK -- they will normally test shorted. I would remove each of the capacitors, one by one, until the short hopefully goes away. Don't remove the inductors.
