Gigabyte 350 motherboard, Keyboard won't work post BIOS update and can't boot

[currynchips]

Hi Everyone,

Not sure if anyone is able to help or offer any advice. I updated the BIOS yesterday on my Gigabyte motherboard.
All went well no errors or anything, but since the update, I am unable to use a keyboard and therefore BOOT into anything.

I have tried another keyboard, I have tried all USB’s and I have even tried both keyboards using a PS2 adapter. But still no luck.
So then I removed the CMOS battery and also did the reset for my motherboard by shorting across the two CMOS reset pins, which I am certain worked as when I rebooted it did a different beep sequence.

I have created a quick video to also show.


Many thanks in advance for any help.

g’day and welcome to the forums.

how did you flash your BIOS, from within Windows, using the Gigabyte BIOS update program or by uploading the .bin file directly from the BIOS config menu?

it may be going straight into BIOS now if it’s not finding any bootable devices, so check you SSD or HDD is connected. also try having a bootable USB stick with a Linux distro on it attached to see if that helps.

it would be good to now reflash your BIOS back to the version it was before the upgrade, and there in lies the rub!

see if anything here helps; https://www.gigabyte.com/MicroSite/121/tech_qflash.htm
don’t suppose even the End key works, as it sounds like no keyboard activity at all is being recognised.
you can’t even turn NumLock on or off!!!

using a Linux distro to get into the PC and then from there, into a command prompt would be the way to go, but useless if even still the keyboard wasn’t detected.

Hi Bruce,

Thank you for the welcome and help.

Good news I actually managed to fix it this morning! Your feedback 100% helped, the steps to fix it were:

Originally updated BIOS from version 21 to 31, this was mandatory according to Gigabyte.
However, once updated I suffered from no keyboard etc, so your idea about bootable media made me test removing the only drive in the PC and NVME.
That allowed me to then access the BIOS by the PC booting straight into it.

I then downloaded the latest BIOS (51) on my other PC and using the BIOS flash tool I updated it to this. Re-installed the NVME and hey presto sorted!

Thank you so much and looking forward to speaking more on the foum.
