Question Motherboard Code 40 fix?

[xd_69]

So I turned on my pc and the just got to the windows login screen where the screen just turned black, it won't detect any of my monitors both Hdmi or Displayport. The code of the motherboard shows code 40 and I've restarted the system multiple times but it won't detect my monitors and the same code appears. What do I do?

The motherboard is a Asus Rog Maximus Formula XI.

Thanks in advance
