Question BIOS Updated - Black Screen

I know there are a lot of these with similar stories, I've tried a LOT of solutions....

cpu is 5600x
motherboard Aorus b450 Pro Wifi
The ram is ddr4 3200mhz Tforce brand
PSU 550w Corsair
Variety of hard drives and SSDs - dont know specs. Windows 10 is installed on one of the SSDs
GPU Gigabyte eagle 6650xt
CPU Cooler just the stock fan

This is a hodge podge of old components from 2018 that ive been updating as I go. Nothing has been physically changed in over a year. My issue is im an idiot and tried to fix something that wasnt broken.... updated BIOS from i believe version 62 to 66g. Everything told me the installation went well, and it restarted when finished. As of now, I've never made it past fans -> a few lights -> beep code -> full speed on fans -> black screen.

Ive got 4 post lights on motherboard (VGA, DRAM, CPU, BOOT) that cycle between DRAM and VGA - ends up settling on VGA. The beep code beeps once (1 beep is typical on a good day). To my understanding, the light settling on VGA indicates there is an issue with graphics.

Things ive tried:
CMOS reset by power off...unplug...battery....wait... have repeated like 10 times thinking it will change.
CLR CMOS by shorting the posts
Removed various sticks of ram one at a time, and in different slots
Tried my old ram as well (some cheap Oloy set)
Tried reseating GPU, plugs, and checked all connections
Tried a different GPU (old Powercolor 4gb rx570)
Tried different outlets/power strips
Tried booting with zero GPU (did get a different beep code 1 long, 2 short)
Tried different monitors and HDMI/display ports

Did my 7 year old motherboard finally call it quits?
 
Looks like it.


A good life's lesson.

New MoBo would be in order. Or you can go with upgrade to CPU-MoBo-RAM. E.g Ryzen 9000-series with DDR5 and AM5 MoBo.
Im already mapping out a motherboard, ram, CPU bundle to get me into a 9600x on newegg.... 350 bucks doesnt seem bad all things considered. Im due for a mass upgrade anyway. GPU should still be good for a while (all i do is 1080p anyway)

Thanks for confirming what I deep down suspected anyway. Probably just needed the push to quit trying to fiddle and just upgrade....

Well, the two things you didn't test are CPU and MoBo.

But since PC got bricked after BIOS update, it most likely is corrupt BIOS.
Though, holy bible of PCs does warn about updating BIOS if there is no need. But i guess you didn't read it. 🤔

Since your MoBo doesn't have BIOS rollback feature and/or dual-BIOS, there isn't nothing to fiddle anymore.

Moving forwards, better to get dual-BIOS MoBo. Since when you get the itch to update BIOS again, you at least have 2nd BIOS where to fall on, if the 1st BIOS update should be bricked again. :)
