I've just purchased a used RX 570 which worked fine the first day of use, but since day two it will turn itself off after two second on boot. The fans start spinning and the "Radeon" logo led lights up but then it immediately goes dark and I get no signal, even though the rest of the system seems to boot.
The card doesn't show up in device manager if I use the onboard graphics to get into Windows. My R9 280X works fine in the same computer. My PSU is a Corsair CX750M which otherwise seems to work fine. I've tried reseating the card and the reconnecting the PCIe power cable around 20 times and two times it has booted normally again, but after I power off the computer the gpu won't boot again. I tried the card in an older computer with the same results (although unsure whether that PSU was sufficient).
So what I've got here is a graphics card that always "dies" during the boot sequence except for three times right after I've put it in. Is it just a faulty card, or does anyone have any ideas?
