so i need to sell my graphics card the rx480 8gb edition.

I uninstalled the gpu. next I plugged in my vga cable from monitor to motherboard, turned the pc on but after the bios the screen turns black.

I then installed my graphics card again and now the pc boots past the bios and works fine. How can I fix this?

Specs
ram 8gb
cpu i5 3570k
gpu rx 480 8gb
