Brought a new Mobo (ASROCK B365M Pro4) and CPU (intel i5 9400) installed them into my pc, my fans are all on, the power button led is on but the USB isnt working, Display has black screen, theres no leds turning on, on mobo and no beepity boops when i turn it on. Been at it for the past 3 hours trying to find a solution. If anyone can help me i would much appreciate it.
