So my m15 R3 (AMD version) improperly restarts every few seconds when booted to the desktop when using (or attempting to use) the AGA. I still use a 13 R3 so nothing is wrong with the AGA itself. I've tried many things from uninstalling/reinstalling drivers to updating BIOS and AWCC. 

So the m15 R3 recognizes the AGA with the Nvidia card in it but side note, I cannot use it with my internal LCD. I think it's now built that way. I don't know nor care because the problem starts as soon as I try to output to my external monitor, then in a few seconds (between 3 seconds and 90 seconds it varies) it'll freeze then suddenly reboot to desktop repeating every single time until I tell my m15 R3 to output display only on the laptop ( FN+ whatever function key, I forget, let's you choose your display preference) quickly before it freezes again and reboots. Since this is a new SKU for Dell I'm dreading no-one having any answers to this yet but I figured to try anyway.
