so i recently got some new parts (i7 8700k, asus rog z370e mobo, 16gb trident g skill ram @3000mhz) and cannot get my rig to boot with my graphics card installed (its an msi armor rx580 8gb). card is fully functioning, as it was tested in a friends computer, and booted fine. pcie slot and vga cable have also been tested and are functioning. psu should also be good because it was able to boot with my friends gpu in it (much more powerful card), so i think it has sufficient power. Updated motherboard and all drivers, also did fresh install of windows 10. i have checked everything and cant seem to get it to boot with my rx580. is this juts some sort of weird incompatability issue? any input or advice would be helpful. thanks!
