Did you test the motherboard for resistance? Was the resistance of different parts normal? Did you do voltage measurement? Do you have all the necessary voltages?

Depending on the condition of the device, the chances of chipset failure are high. If it has graphics(DIS), first reboll the graphics and then the pch.
