Я не знаю эту карту, но она, вероятно, сзади.
I was looking for the 5 volts because I believed it was missing in the nc671 vcc, but the image you sent clarified me a lot, thank you very much.

in this case, first you need to find 1.8 volts. after the formation of this voltage, the rest appear. Check the chokes PL1 and PL3. one of them will ring on 8 pin BIOS chip, this will be 1.8 volts. the other will form 5 volts accordingly.
yes the PL1, is connected to the bios chip but without voltage.

measure the resistance at the chokes pl1, pl2, pl3, pml2. write the result here. we’ll think about whether to repair this card at all.
after I saw the image that the mikazuki sent I checked the resistance in PL3 and it was 56ohms, that is very low, so I tried to inject 5v into the coil and I felt a slight heat in the GPU, did I end up killing the gpu or the she would already be dead, but it wasn’t supposed to reach 5V, right? I removed the gpu anyway, so I could inject the voltage and see if I can find out where the short circuit is, at least for the sake of learning.
PL1: 880 ohms (now without the gpu)
PLM2: 55ohms
PL3: 15k ohms
PL2: 970 ohms

ps. foto is too bad
Sorry, next time i will try to send a better picture
Is this resistance so low?
and thank you all for your help.
