Graphics card: MSI rx 580 8gb

When I insert graphics card, monitor and other peripherals are not working, i don't know why.
I am 99% certain that the graphics card is legit and working.

I do NOT hear any beeps or unusual sounds when i press power button.

My power supply is good and has 730w so it is strong enough to power rx 580

But, strangely, my PC is working when i pull out my graphics card (system is running on intel hd integrated graphics then)

Any help to fix this?
