I just built a new computer and it would not boot (even into BIOS) with GPU plugged. I unhooked the GPU and it booted fine.
I went into BIOS setting and PEG was selected as default. If I switch the boot mode to IGD, the computer will boot fine, even with the GPU plugged in.
Booting in PEG with GPU plugged in - does NOT work
Booting in PEG WITHOUT GPU - DOES work
Bootiing in IGD with GPU plugged in - DOES work
Booting in IGD without GPU plugged in - DOES work
My set up-
CPU - Intel i7 6700
MOBO- MSI z170a
GPU - MSI GeForce GTX 1070
Memory - 16 GB HyperX Fury
OS - Windows 10 64 Bit
