My PC: A320 mainboard, CPU A10-9700+onboard GPP+12GB RAM+650W PSU. All run normal. So my brother gave me his old RX570 4GB since he's not using it for a long time. After i plugged the RX570 in and pressed start, this happened: the new GPU started, its fans started, and then the fans stopped. After around 5-15 minutes, my pc rebooted. That repeats until I unplug the RX570. Do you have any idea what was going on?
