So my gpu r9 380 asus strix stopped displaying and giving just black screen not even "no signal" is appearing.Itnis not software problem i tried everything. when gpu start it failednto boot with 3 outcomes First gpu load fans at 100% Second gpu dont spin fans at all and third gpu spin fans normaly but often stop and then start to spin again and then after some time start fans at 100% . in all of 3 cases gpu failednto POST i checked gpu voltages on pci x16 and all of them were good exept 8th pin (aux) it should provide 3.3v but it provide 0.250 volts should that be a problem?
