Question My rx570 disconnects lights and fans are still on

[R4ske]

Hi so I bought my RX570 off used market and now when I try playing honkai star rail on high my gpu disconnect and screen turn black and you can still hear song or game running

so far I try drive changing, flashing bios, changing thermal pads and paste and bought adapter 2power sata to 6pin
before I had gtx 1070 and i run fine for year and half

my pc configurator is

i5-4670

16gb of dd3 ram

psu IG-MAX 5600 SIXTUS 600W

gpu model is RX570 4gb nitro with 6pin and 8pin connector

update the motherboard´s bios

try a different PSU

try gpu in a different sytsem

use ddu uninstaller to delete all nvidia drivers and amd
reinstall amd drivers

gpu might be faulty

my motherboard bios is updated and I did ddu am undervolting my gpu for now it works fine
if it is a psu problem I don't really want to go out to buy a new better one because this gpu i pay only 30eur for it
I use this gpu just to have anything better than gt 1030 while saving up to buy a more modern pc

tnx for advice on how to fix it
