I tried pulling out cpu from my old mobo (system worked fine before shutting down pc). So i also have an old system, 1060 6gb, ryzen 5 3600, msi b450m pro-vdh max, some corsair vengeance lpx 16gb kit 3200mhz. It didn't so I've q flash plus, installed new bios, which idk if it was installed correctly, cause after i put everything back, it's doing the same thing, fans spinning, but no video output, i tried plugging my 1060 in to see if it's not the hdmi port on mobo, but it's the same. After building it, my pc didn't put out video output to my monitor, so i checked if the mobo supports 5000 series out of a box. I've bought a new ryzen 7 5700g, new mobo aorus b550m elite master, and ram corsair ripjaws 32gb kit 3200mhz cl16 to have new pc, I've used my old psu and case.
