What graphics driver did you install? Free drivers I don't think will work (ie nouveau).
If you wish to use your nvidia card I would recommend you select the proprietary bumblebee hybrid driver
or for the sake of simplicity, to get your installed system to boot just, select the intel driver
and the hybrid driver can be installed post install if you wish.
Booting from the ISO I assume you tried non free graphics drivers? I don't think free drivers will boot with this machine.
You shouldn't need to re-install your system just to change the graphics drivers installed
Boot into your manjaro-architect ISO and from the CLI chroot into your installed system, where sdXX is your root partition
sudo mount /dev/sdXX /mnt
sudo manjaro-chroot /mnt
Now check which mhwd driver is installed
I just did this with a Virtualbox Manjaro VM, it worked well.
To install a different graphics driver using mhwd, remove the current one first, then install the new one. For example, if you have nouveau installed and want to replace with nvidia bumblebee
sudo mhwd -r pci video-nouveau
sudo mhwd -i pci video-hybrid-intel-nvidia-bumblebee
If you have nvidia bumblebee already installed and want only the intel driver to get your system booting
sudo mhwd -r pci video-hybrid-intel-nvidia-bumblebee
sudo mhwd -i pci video-intel
I assume you installed the 4.11 kernel, to check
If not then you can install it using
sudo mhwd-kernel -i linux411
Also, for the manjaro-architect ISO CLI you can run diagnostic commands
journalctl -p err -b
Pipe the results into text files, mount a USB drive, copy them, and post them here.
You can also check your xorg logs for errors in
/var/log. Copy them and pastebin them here too.
Before you do all that piping and copying though, make sure you have the correct graphic driver installed first, and try booting into it.
