My pc was struck by a power surge along one of our imacs, the imac tries to start but turns itself off the whole time. And my pc has a worse problem. Everytime i try to turn it on. It makes a little "Ting" sound and then only lights up my ram (corsair vengeance) my fans dont spin, rgb strips dont light up. Just my ram. I have a gigabyte aorus gaming 7 x470 with a ryzen 7 3700x (motherboard has had a usb flash bios update) a day before the accident everything worked. Motherboard lights lit up, fans worked. I tried some things like resetting cmos but it didnt work. Im lost guys and i need help badly. Psu is a corsair 850 watt gold rated power supply. The motherboard power and cmos button on the IO stay lit up. So i fear its my psu. Any thoughts?
