New AMD ryzen 5900x not displaying any input

[Rysahn]

So I get a new CPU and update my bios using the handy HP assistant tool and I install my new CPU with ease but only to reveal that my PC now won't display anything. I'm not a truly experienced builder in PC's but its installation was not hard and followed guides to boot as well but the only thing my pc is capable of doing is running with all the LEDs on but no display. I've seen many things about BIO CMOS RAM cleaning and PSU problems but I don't even know if my Motherboard is actually compatible and I suspect it's probably not. my Motherboard is a Higos 2 84f6 and I can't find anything about it other than its obscure name. 

Help would be good but I'm not hopeful that my new CPU is gonna work which means I just bought an expensive paperweight thanks in advance

this is probably your motherboard:

Thanks for the help and in terms of my motherboard specs I couldn't even find a thing on here and if i did it would boot me to a error screen. I think it's time I built a new rig anyway I'll just strip out the components that I've already upgraded my pc with and start a new.
