content: The board is MSI Z170A XPOWER GAMING TITANIUM EDITION. I have debug LED's on the motherboard that shows 2 digits and the digits were "00" (not "0D")..  The PC appear to work normally, including the fans and the status LED's on the motherboard. I also pulled hard disks, and any USB device from the board, but to no avail.  When I refer to not booting, I mean completely inaction of the CPU to boot anything.  I know when the BIOS gets loaded because I see different numbers appearing in those motherboard debug LED's. After it boots then it shows the CPU temperature.  But this situation literally nothing happened. Black monitor, no BIOS startup screen, no response of the "DEL" key to go to BIOS.  Also something else I noticed, when I flipped to the other BIOS then Windows did boot up but no keyboard but I saw it installing drivers (mouse). But the keyboard was dead. I had a windows, I could use the mouse but unresponsive keyboard. It took multiple reboots before I got my keyboard control back. Other things that were clear was that I have Windows drivers reinstalled in my native language and not how they originally were in English. So it is very clear that drivers were reinstalled, again pointing towards a Windows 10 update that caused the issues. The fun thing is that I on purpose bought this motherboard because it had 2 BIOS in case one got crippled by ransomware. On top of that last week I reported that a forced Windows 7 to 10 migration bricked my fathers Windows 7. He asked me if he would go to Windows 10, but I warned him that I had Windows 10 and have many issues with it (clock incorrect when I boot up, crashes when I press the start button,...). I did not get hold onto my father but last that I knows wash his network connection was crippled.
