[SOLVED] My pc starts but the mobo dont show the bios

[Mannick]

msi x570 a pro

seagate barracuda 2tb
nvme 970 evo
5700 rx
3700x ryzen
seasonic focus 850W

When I turn on my computer, it only shows a black screen, the computer is on, I have already tried changing the graphics card and the CPU but nothing happens, only with the main power supply of the board and the 8-pin for the CPU does not give power by no usb to keyboard or mouse.

New, or old setup? Why changing CPU and GPU, but not motherboard?

To be able to get into the BIOS, you need to connect all power to the motherboard (24-pin ATX, 6-pin ATX & 4-pin ATX power connectors) and the GPU (8-pin PCIe & 6-pin PCIe power connectors ).
