5th model 3330 fails to start with GPU attached (GIGABYTE GA-B75M-D3H)
You're facing issues getting your GIGABYTE GA-B75M-D3H board to boot using the IGPU with a GPU in the slot, even without CMOS. Try checking the power connections and ensure the GPU is properly seated. Also, verify that the board's BIOS supports IGPU mode and that the chipset is configured correctly for it.
It's typical for a board to turn off the IGPU when a PCI-E GPU is detected. If you need to use the IGPU, simply remove the PCI-E GPU.
Verify if the BIOS includes a setting to adjust your preferences, if not yet configured.
