Unresponsive computer (black screen) after failed bios update via Windows Update

[Tubelix]

I updated the "HP Firmware" on my HP Pavilion Gaming Desktop PC TG01-2000a via Windows update. After this BIOS upgrade from inside Windows 10 via Windows update, the computer is now unresponsive. The computer restarted a couple of times but BIOS upgrade screen never showed up. There were no visible errors or beeps. Only a blank/black screen.

Now when I power on, the computer is unresponsive and the screen remains black (no signal). The computer was functioning correctly before the BIOS update. I have tried a hard reset but it did not change the situation. I have also tried the Windows key + B + power key and the Windows key + V + power key but no luck. It simply displays a blank/black screen and flashes it's green LED on the front.

Expert advice and help are greatly appreciated.

The strangest thing. I hooked the computer up to totally different keyboard, mouse and monitor, and the BIOS upgrade showed up and I got it updated without any trouble. Have no idea what was the cause of the problem. I then hooked up all previous peripherals (keyboard, mouse and monitor) and now everything is working as it should. I will avoid updating BIOS or other firmware via Windows Update in the future.
