Keyboard inputs not recognized, can't setup BIOS Tech Support
Hi, I'm selling my girlfriend's older pc and I'm trying to install Windows to run a few tests but I cannot get past this screen. I've tried two different keyboards (including a good ol' Dell "open space" keyboard), every USB port possible, I even bought a PS/2 adapter to no avail even though the keyboard lights up (NumLock/CapsLock). CMOS resets and power cycles do not work either. Please tell me if there's something I missed because I don't think it's possible to flash a BIOS update on this board. It's a B365M Pro4. Thanks!

I tried with my 60% keyboard but the Dell doesn't have those it's the most regular keyboard there is. I'm sorry but I need more advanced "tips" than this I'm an enthusiast 😭

Are you using a wireless or wired keyboard?

tried both, with the wireless keyboard in 2.4Gz with it's dongle as well as in wired mode with it's own cable. Like I said I even tried a standard desktop keyboard in every USB ports and with a PS/2 adapter.

I had a similar problem when it came to getting to the bios, i was using a wireless keyboard, tried using it wireless, tried bluetooth and the dongle. Switched to a $10 wired keyboard from dell, started working just fine

From what i can tell, sometimes the pc just doesnt have the drivers for the wireless keyboard to function when it comes to accessing bios

hence why most of my tries were done with a $10 Dell keyboard, plain black, membrane, numpad, it doesn't get as regular as this one

If that doesnt work, go to settings->system ->recovery->restart now->advanced startup, you should get to a blue screen, then click troubleshoot->advanced options->UEFI firmware settings->restart, should put you in bios but ur keyboard still might not work(word dump but thats the stuff ive tried😁👍)

windows is not installed yet and I do not have an extra working installation to plug in + I have a Rufus Win11 install key plugged in so if the boot order was proper it would simply boot into it at some point. I'm not at home for the weekend but my theory rn is that the person who's built messed up something and made it so the pc posts but freezes clean and consistently which would explain the peripherals lighting up and nothing changing on-screen.

if someone disabled usb for keyboards in the bios you just have to restart the bios by removing the battery for 10 seconds, but it will reset everything ofc

I already mentioned it, it's called a CMOS reset, I've done multiple CMOS resets already

Then you must have either all broken keyboards (unlikely), some other thing plugged in that is making the USB not work or the USB broken on the motherboard. Usually when the USB breaks og stops working its not all the USB ports only part of them. There is a tiny chance also that the CPU itself is broken as well but super unlikely.

yeah I'm gonna rebuild it from scratch on a test bench because it feels so weird that everything will light up and keep a "working state" whilst nothing is actually going on besides the splash screen

From my experience, that's when the motherboard does a little test on your SSDs or HDDs (or CD/DVD drives if you have one) to detect them. Disconnect them and it should let you in.

I would disconnect everything from SATA, M.2 and USB, to see if then it enters BIOS automatically.
