PC POSTs but no display

[dductt]

hello, i have replaced my motherboard, cpu, ram today. (and i have installed a new m.2 nvme ssd)

 

when i boot up the pc, it goes through the normal boot process, it posts but there’s no display on my screen(s).

 

 i have tried clearing out the cmos battery, tried swapping ends of the cables, tried 1 DP and 2 HDMI cables, tried it on 2 different monitors, resetting the monitors. (yes, it’s on the correct input)

 

gpu: gigabyte rx 570 8gb

motherboard: msi b550-a pro

cpu: ryzen 5 5500

ram: kingston fury 8x2 3200mhz ram

 

help will be much appreciated!
