content: Windows 10 update probably trashed my BIOS Last week my fathers computer got crippled because of a forced migration from Windows 7 that failed.  Since yesterday my PC does not boot anymore, my FLASH display (MSII) shows "00" and does nothing. The fans run like normal but that debug display does not show any movement. There is nothing wrong with the PC since this motherboard has a second BIOS and it boots perfectly. That BIOS was still on version 1.50, the one I booted up with is V1.70 (I upgraded that one last time but kept the v1.50 just in case). I have an emergency USB flash port, but it seems not to like my USB flash that is >4 GB. BIOS Flashback+ doesn't start. I am probably not the only one that had this because a family member also got the computer BIOS bricked by Windows 10 a few month ago. He had to get a new mother board. Edit: My board is: Z170A XPOWER GAMING TITANIUM Flashed back my BIOS and Windows booted up again. I have no doubt that Windows 10 update thrashed my BIOS. BIOS B trashed after I shut down Windows 10 and I booted it up in the morning. Booting up with BIOS A (E7968IMS.150) booted up Windows. BIOS B stuck with debug LEDs "00". The fans work but the computer is dead. (I had some issues to make the MSI M-Flash recognize the USB dongle. To my surprise it recognized the 256GB version and not the 2 older USB dongles that were 8 GB.) So I booted in BIOS A --> BIOS screen, went to M-FLASH (it rebooted into FLASH mode), flipped the BIOS switch to BIOS B (without powering off) . Then flashed the E7968IMS.170.  Reboot went successfully and I went straight into Windows 10.  Update: After I reflashed the BIOS no issue whatsoever. So it is clearly not an hardware failure. Update 2: The is no doubt anymore that a Windows 10 update bricked my BIOS and crippled my motherboard. Deep scan of any virus turns out nothing, and the PC is running like charm after I reflashed the BIOS.
