Just started happening with blue screens recently, then it wouldn't load windows, rested with only one gpu in and that worked, then put second hack in and windows worked, restarted and audio wouldn't boot with the pc, just reinstalled and it blue screened again after nstalling windows and loading the setup screen for computer name etc. Also got 0x9c once, but mostly the 125 blue screen. Gpus appear fine, reset to defaults in bios so either mobo or CPU right? Edit: just noticed one of the gpu fans are spinning up alot then going down in speed again, almost confused about fan speed. Also before I tried a reinstall, the mouse and keyboard would not work at windows, but did in bios THIS ONLY STARTED HAPPENONG SINCE AMD 13.2 DRIVER UPDATES!!!
