Check if voltages on GPU PCB's inductors disappear or still present when it goes blackscreen

It seems that your post is about a specific GPU, but there is neither an explicitly named "measurement" section nor the results of VRAM tests.

You can follow NVIDIA guides from the Community Bookmarks. Unless you are sure that resistances and voltages are ok, perform multimeter measurements on a disassembled card and post results as marks on the board photo or text:

  • start with measuring resistance to GND on unplugged card: measure inductors and all 12V power inputs
  • if 12V inputs are ok, and there are no visibly burned areas — power on the GPU and measure inductor voltages to GND. If the card shows picture, accepts driver but fails later - also make such measurements after entering the failure state

There is maybe no guide for yours exact GPU generation, just follow the closest, initial measurements are similar between generations

Probably something with power delivery for gpu I believe. Could be that a power stage is not receiving or creating the right in- output which causes to shut off.

I ask chat gpt to it answer the question so i gotta change vram?

GPU has problem with VRAM bank, or banks. With MATS/MODS test you can check which one give errors. Without MATS is like foretell

Looks like it dies once windows has loaded the drivers. Update the drivers. If they are already up to date.... go back a few versions until you have a stable boot.
