I was using the 20H2 version of Windows 10 when a pop-up on the desktop asked me to update Malwarebytes (I've scanned prior to that, so it isn't a malware).
After updating and restarting, my PC couldn't boot into Windows. I can't get to the BIOS or Recovery Mode because my keyboard only starts working way before the POST.
Also, there is no video output on VGA and a black screen on DVI-D.
