Hello I have to the z490 gmaing plus an intel core i7 10th k a gtx 1050ti and corsair vengeance rgb ram (3600). Nothing works everything sits properly inside so mainboard should work I think because on my kolink obsevatory (case) a blue led lights up even when I unplug the diereckt connection from the case to the power supply. The graphics card works, it was also installed in my old PC. I can also rule out the power supply as it also makes power noises. Can anyone help me with this problem?
