ryzen Black Screen on BIOS

RubberEyes · August 30, 2019

Me and my friend recently bought parts to make a good PC for him. We have a Ryzen 3600, with 8Gb HyperX for RAM, a Seagate HD, a Kingston SSD and a GTX1660 on a ASUS B450-M Gaming.

We put it all together and... Nothing.

Just a Black screen. Okay, no panic.

We knew that the 3rd Gen might not have been compatible with the motherboard straight out of the box. Fortunately I have a Ryzen 2400G (with 2x4Gb Team Group Dark Knight, no discrete graphics on a Gigabyte A320m-s2h). We do some tests firsts. Taking parts from his PC and putting them on mine: RAM and GPU are fine. After a BIOS update on my Gigabyte we confirm that the Ryzen 3600 is also working.

We take my CPU and put on his motherboard. Can't access BIOS, it only gives us a black screen, but can install Windows. Installed Windows and ran it ok. Try to enter bios through Windows, but this motherboard apparently doesn't support that option.

Then we do some playing around. We have 2 monitors and a TV, so we try to connect all of then, into every port available at least once (I had read of someone who only could see his bios when connected to a TV). Nothing. Every time, when we turn the PC on, we see ASUS logo, the text saying to press DEL or F2, and if we do press any or both, we see a Black Screen with nothing. Any ideas? Is there something 'protecting' the bios? A jumper we forgot to use? Or remove? Is it just plain defective?
