[SOLVED] Ryzen 2200g mobo b450 does not work

[marcopoloceco]

Hi guys,

Ryzen 3 2200g
Gigabyte b450m ds3h / asus b450mk

Fury hyperx ddr4 8gb 1x
SSD
Seasonic 600w

It is low-end new pc for kids, all is plugged ok, but no signal to lcd, no beep (these mobos are without beeping - dunno)
Fan ryzen works, same like fan of case. But it is all..
Changed SSD with normal HDD and it is ok too.
But no signal (hdmi and vga) and probably no boot..

Bought 2nd mobo and the same problem

Eatx power cable for ryzen is plugged.

Do not want to pay same computer twice, until i’ll find out bad part..

Lcd is ok with another pc.

Thanks for ideas, R.

By lcd you mean tv, or monitor?

on gigabyte it work with bios f1 and on asus you need bios 219 https://www.asus.com/Motherboards/PRIME-B450M-K/HelpDesk_CPU/ asus use dvi-d https://www.diffen.com/difference/DVI_vs_VGA and no hdwi from specs also it need a 8 pins tx with the 24 pins ones same for the gigabyte on power request .

Monitor, sorry.
Not just one, but two..

I did almost the same comp a few months ago (different ram and mobo was 350 - flashed it) and it was done in hour without problems..

Maybe bad psu - power just for fans..

Problem is, that older asus 350 is without beeping too (speaker plugged) - so i do not know if problem with memory etc.

try to only use one monitor at the time and does board show any debug led or code on them .
