ok i made PCI-E the primary
here are the connections i've made:
VGA from Monitor to Mobo
DVI from GPU to Monitor
the power situation with the GPU is weird
my PSU has 6pin power cables but theres a little cable connected next to the 6pin which is 2pin
so i figured this was a way to have one cable for 6pin and 8pin
When I reset after making the PCI-E slot primary, nothing changed. The GPU fans still aren't spinning, and the POST beeped once
EDIT: i reset again, the POST beeped only initially
