EXP GDC Beast mini-pcie black screen on both displays (laptop and monitor). It won't boot and the unit turns on (PC and Beast) both have power but there's no display output. When I unplug the mini-pcie from the PC, the screen turns back on after reboot.
I have an HP EliteBook 2540p with i5 6gb ram and SSD and I am attempting to install a Nvidia GTX 660 2gb
Didn't go to into bios, or change any settings, also my EXP GDC Beast have 2 switch - atx off/on and ptd, which are both off, tested with ptd on but still black screen
