BIOS not detected - help!

Hey there, everyone!

I ran into a rather bizarre issue with my PC today. It all started when I unplugged an older E-Blue Gaming Cobra 2 keyboard after a gaming session. Once I finished playing, I decided to uninstall the game and wipe all its leftover files from the system. I gave the computer a quick restart, and that’s when things started getting weird.

First off, the Windows welcome screen just kept spinning indefinitely. I eventually managed to get past that, only to be hit with constant error messages stating my keyboard wasn't supported. I finally unplugged the device entirely, but now I can't even get the computer to boot up properly. To make matters worse, when I enter the BIOS, the boot screen is suddenly filled with these strange, unreadable symbols—it looks like total gibberish. Now, every single time I turn the machine on, I have to mash the F11 key just to bring up the boot order menu so I can manually select my drive.

I'm running Windows 10 Enterprise, and I've attached some screenshots so you can see exactly what I'm dealing with.













I would truly appreciate any help or advice you can offer.

I can't see any images here. Check if your CMOS battery is actually hitting 3V. If it isn't, just swap it out for a fresh one and try getting back into the BIOS.
Since all those BIOS settings live in the CMOS, a dying battery will make everything go haywire...
Don't forget, once you pop a new battery in, you'll need to fix the time and date, probably switch the HDD controller over to AHCI, and set your boot order again.

I can't seem to edit my previous post, so I'm re-uploading the images here.

Last night, I tried restarting the machine, went back into the BIOS, and suddenly it just wouldn't boot up at all. It was a real headache! The only way I could finally get it running again was by unplugging every single cable and then reconnecting them. But now, there's a catch. Every single time I power on the system, I have to manually hit F12 just to access the startup sequence.
