Question I think I may have broken my motherboard ?

[yanna1]

Hi,

I put together my old system to hand over to my son. I bought a new ssd and the other parts are around 3-5 years old.

I got everything put back together perfectly and installed windows 11. I let Windows do its updates and I was feeling pretty good about my self. Things went so well I thought I would update the BIOS from F40 to F67b.

I used q-flash through the bios and everything seemed to work fine. It got to 100% and it said "the system will now restart" It did exactly that but now I am stuck on the Aorus Splash screen and I have a red VGA light on the motherboard.

It just show the logo with the options along the bottom are
Del:bios setup/q-flash
F9:system information
F12: Boot menu
end:Q-flash

I try using the keyboard to select an option but nothing happens. I just cant get passed this screen or into the bios.

Things I have tried....
New HDMI cable
GPU in another pc(works fine)
Tried another 8 pin cable

Does anyone have any ideas or have I just bricked my motherboard?


AMD Ryzen 5 3600
Gigabyte B450 AORUS M
Corsair 16GB (2x 8GB) 3200Mhz DDR4 Vengeance
Gigabyte GeForce GTX 1660 Super
PSU - 650w Seasonic Focus Plus Gold(5 year old)
Crucial BX500

You forgot to mention the make and model of your PSU and it's age. Clear the CMOS. In order to do so, you disconnect from the wall and display, then remove the CMOS battery, press and hold down the power button for 30secs and replace the battery after 30mins.

Sorry about that. Its a 650w Seasonic Focus Plus Gold(5 year old). Thanks for advice I will give it a go in the morning with fresh eyes.

Sadly this never worked. I heading out later so will try it again for a bit longer than the 30 minutes. Thanks.

Still no luck. Any way to go back to the previous bios?

Attached the wee internal speaker and I get a single beep. Guess that's a good sign but I am still stuck on the bios flash screen. No matter how many times I hit the delete key I still can't get into the bios. Tried all the other usual keys and confirmed the keyboard is working but I can't get any further on.

Personally, given the VGA light I would first try a low-powered GPU in one of the PCIe 2.0 slots. It can be really old and slow but best if it doesn't require auxiliary power. Then I would try different USB ports for the keyboard (especially the USB 2.0 ones) or even a PS/2 keyboard, as you have a PS/2 port. Leave the SSD disconnected during troubleshooting as the now default BIOS settings may not be what the system was installed with, + you only want to enter the BIOS for now and not accidentally load Windows.

Your board has dual-BIOS with two actual BIOS chips, so you can look up the datasheet for those chips to determine which pins to short or lift to disable the primary BIOS and boot to the backup--normally it automatically goes to the backup if a problem with the primary is detected (like no firmware being in it), but if the primary looks good and begins to load only to crash afterwards, well that's where it will get stuck.

Once there, you can reconnect the primary on the running system and try flashing the new F67d BIOS that just came out to it. Usually the manufacturer flash tools will only flash the primary BIOS chip while booted to the backup chip. Good luck!

Thank you for getting back to me with some good suggestions. I don't have to hand a lower powered GPU but I may be able to get a keyboard with the ps/2 port connection.

I was wondering that maybe the back bios is kicking in automatically. I'm sure some B450 motherboards required a bios update for the Ryzen 3000 series. Maybe the back up bios is that old that it doesn't support the CPU anymore and I would need an older CPU to update the bios to one that supports the 3000 series. Does this sound possible? However because I actually get to the flash screen would that rule that out. Also no motherboard CPU light is on just VGA.

Thanks

Just to add.... I did try the GPU on the PCIEx4 slot but got the same result. Stuck on flash screen.
