PC Won’t POST, No Display. (New motherboard)

So my problem started a week ago. My pc just got a bunch of BSOD with error codes like "page fault in nonpaged area" and "irql not less or equal"

I started to try with just 1 or 2 ram. I reached windows reinstall but after that I installed firefox and everytime I tried to turn on with any method the system was off. just Bsod all time. It was with Asrock b360m pro4 mb.

I tought the problem is with the motherboard since I tried with all my ram out in every slot.

today new motherboard arrived.

ASUS ROG Strix B360-G Gaming. I did reset bios, battery, built everything together.

My new problem is that I cant reach POST at all. Its just black screen and thats all. I connected keyboard and mouse but there is only small light on keyboard. its start to glow usually after atleast I reach BIOS.

So I built everything together, again tried to start with just 1 ram, leds and fans running, in VGA and everywhere. I tried to connect screen to motherboard but there is no screen or starting at all. its not the problem with it.

CPU: Intel Core i7-8700

GPU: XFX RX 580

RAM: G.Skill Aegis, 4 sticks 8 gb each

Motherboard: ASUS ROG Strix B360-G Gaming

I have no idea at all. My idea is that maybe its the cpu not the motherboard... but I afraid to say that. just bought that motherboard. Have no clue at this point
