Hello, I changed my motherboard to Gigabyte Z170 K3 couple of days ago and after that I started to have this weird and annoying issue when I turn off my PC or put it on sleep mode and try to restart it again fans and lights turn on, but nothing happens, screen just stays black and I have to unplug the power cord before I can start it normally again. Everything is default on bios and other than that it works normally without any issues.
