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 or B1)
AMD Ryzen 5 5500 6 Core/12 Thread AM4 CPU
I have tried removing the CMOS battery and replacing.
I've checked all voltages from power unit and all are correct, so I don't think its a voltage issue. Must be either M/B, cpu or ram. I suspect m/b.
I have suscessfullt previously built a few PCs (one last week using B550 Phantom Gaming4 MB) without problems.
Please point me where I am going wrong.
