I managed to get WT751002 which is a power supervisory chip equivalent to ST9S313, but whhen I measured the IC input voltages there where no PGI , and all other voltages to the chip where ok , i guess that means that the problem is not with the chip. Right? what supplies the PGI to the chip? do you have schematics or any hint please? I work with GPUs this is my first time to work with PSU

Or could it be a bad chip shorting the PGI input! your help would be appreciated.
