When the current was debugged to 2V and burned, it immediately became more than 4A. I touched a chip PU18 SA with my hand to supply power, and removed the re-burned machine, but there was no current. First change the SA chip, then continue to change the CPU and graphics card, and restart the current of 1.85-1.96-2.15-2.43. There is no power failure, so it is installed and tested, and the machine lights up perfectly.
