It booted once than completely darkness.

I have a desktop PC with gigabyte z390UD, Intel i5 9600k with integrated GPU. For the first time ever I successfully installed Catalina with clover but after a reboot the PC have no HDMI signal at all. I can't even see the bootloader but the PC seams to work correctly as leds light up and makes normal noise. Did I make something bad? Could be a software problem or is dead hardware? Is related to hackintosh or just a case? Thanks I don't know where to start for solving this
