Pc crashed while making an bios update

[NilsDosenFutter]

My pc crashes sometimes random and sometimes it wont boot so i just start again, but it works most of the time, normally it wont crash for weeks, so i thought maybe an bios update can help to prevent that and then i play mfs2020 it allways crash to the desktop and i read an bios update can fix that to, i allready disabled windows automated restart.

my bios version was from mid 2019 so i just try to update it, around 50% into the download my pc just crashed and now when i start my pc i get black screen but pc is running and still have the fan curves that i have before but just black screen.

I allready tried some things to fix that reseating ram, put out the cmos battery and let it outside for more then 20 min and pressed on the start button so all electricity was gone still dont work

 

So just buy a new motherboard ?

 

My Pc 

asrock B450 Steel Legend

Ryzen 7 3800x

16gb ram

2070 super

600 watt 

1tb nvme ssd

 

i apologize for my bad english

have a great day

You could research to see if Bios Flashback is a viable option for bios recovery. Once you've recovered the bios, the board should post again.

AsRock has no other option for bios recovery.

 

I would strip the board completely. Take everything off it.

Set clear cmos batter removed all cables removed. a few hours, over night w/e. 

 

Assemble out of case on the table.

Cpu only, one stick of memory in the corresponding slot to the manual. VGA, and obviously the necc power cables.

 

Plug in the little diagnostics speaker. If it beeps, that's a good thing. 

Follow below drop down in my signature, AMI beep codes is what you look for. 

If it doesn't beep, nothing happens only fans spin. Warranty/replace the board.
