I bought an second hand rx 570 8GB and when i startgame in fortnite, gpu make one colored screen and then entire system crashes. So i tried furmark and unigine, but gpu went well there, as did half an hour of ethereum mining. I tried underclock memory, core and voltage, but nothing helped. I tried to flash bios, but then it did 43 error, so i reflash it back, maybe its because there wasn't xfx rx 570 XXX edition bios, but only black edition bios.
PLS HELP
