I have built a new PC on the A520M Phantom Gaming 4 motherboard, and it won't boot into bios - absolutely no dsiplay at all.

Not yet loaded windows as cannot get that far.

I switch on, press power button and lights come on, fans run but that is all.
I have no additional boards installed, and even removed the USB connections. I have tried both HDMI and DP video out.
Items installed are -
A520M Phantom Gaming 4 motherboard
500W GameMax RPG Rampage 80 Plus Bronze PSU
Kingston FURY Beast 32GB (2x16GB) 3200MT/s DDR4 Memory Kit (with both and one stick (slot A2 & B2 - or only B2)
AMD Ryzen 5 5500 6 Core/12 Thread AM4 CPU

I have tried removing the CMOS battery and replacing.

I have previously built a few PCs (one last week using B550 Phantom Gaming4 MB)

Please point me where I am going wrong.

From what you posted, you have no video card installed. The Ryzen 5 5500 has no video capability, so you need to add a video card, or swap the CPU for one with integrated video.

Therefore why does the motherboard have video outputs.
In any case, before stripping all accessories off, I had a EVGA Geforce GTX970 installed - still no video?
