I'm at my wits end with this problem. I've tried absolutely everything I can think of and if someone can help me resolve this, it would mean a lot to me and save me from replacing this computer. -I have a Gigabyte GB-BXBT-2807 motherboard (technically a barebones style pc build) -This motherboard finally got a firmware update for the Spectre/Meltdown CPU exploits so I installed it (bios F9) -Immediately after updating the bios and after rebooting Windows 7 stopped working. When I try to boot into Win7 it says Windows had problems and needs to be repaired, but it can't finish the repair for some reason. -I decided to re-install Windows to attempt to fix the PC -When I boot the PC from the Windows disk, the moment the Windows 7 installer comes up, the keyboard and mouse both just shut off. They both work in bios, but not within the Win7 installer. Anyone have any ideas for me to try? At this point my running theory is that the newest F9 motherboard bios is bugged and has destroyed this PC's ability to run Windows 7. I'm really not positive though so any suggestions would be greatly appreciated.
