I cant boot my PC at all. Yesterday it worked fine, i dont know what happened. You can see in the video what happens. I turn it on, white light blinks, Gigabyte logo flashed for a second and thats it. Even the fans stop. Theres no signal to the monitor. The monitor works, i checked on the other older pc. I cleared CMOS, checked the cables and all that, still the same. Any suggestions are welcomed.

Specs:
Ryzen 5 2600
Gigabyte RX 580 8GB
Gigabyte x370
8GB DDR4 2666mhz
Thermaltake 500w smart RGB

Graphics card white LED

I found a problem. DVI cable or port from the card to the monitor stopped working. HDMI AND DP work.
