This is a BIOS Power-On Self-Test (POST), Video Graphics Array (VGA) error. It may occur when there are multiple GPUS on a motherboard and an abrupt shutdown of Windows 10. The abrupt shutdown may prevent the BIOS from initiating a proper POST. This, in turn, may force the motherboard to reset to default values. The reset turns off 4G Encoding and resets PCIE Speeds — all of which lead to the Blinitializelibrary failed 0xc00000bb VGA POST error

  1. Disconnect all video cards
  2. Boot into BIOS by pressing F2
  3. Change BIOS settings to Multi-GPU friendly ones per our Asus Prime Z270-A BIOS Mods
