Hello all. My eGPU setup consists of a GTX670 on my Yoga 2 Pro (1.8ghz Haswell, 8gb RAM, Intel HD4400) with the PE4L and an M.2/NGFF converter (the only free mPCIe slot is my WiFi card's M.2).

I hooked up my eGPU. PE4L, adapter, and PSU, restarted my laptop, and without anything extra it just booted up and worked! However, after I restarted my computer (letting Windows 8.1 install the correct drivers), I get up to the windows loading screen and then the screen goes blank - my laptop is still on, but there's no display output on either my internal or external monitor. To fix this I have to disconnect the eGPU, forcing my laptop to boot using the integrated graphics and the internal monitor, uninstall the NVidia drivers, and reboot - only to have Windows reinstall the drivers and repeat the cycle.

Does anyone have any suggestions as to what I can do? I've installed Setup 1.3, but anything I do in that doesn't seem to fix the problem - but I could very well be missing something. And it's kinda pointless to do all this effort to set up a powerful eGPU, only to have it run on the default Windows video driver! I'm assuming I'm doing something wrong with the driver installation, but I'm not sure what. Thanks for your help in advance!!

EDIT: and yes, I've read through all the FAQs and guides I could find - but feel free to call me out if you think I missed something!

I am trying to install an egpu to my lenovo yoga 2 pro through the ngff. My M.2/NGFF converter (P15S-P15F) is not working properly, since my egpu's fan aren't even spinning. I was able to use the same set (Nvidia Geforce 750Ti, EXP GDC Beast dock, working PSU) on my Toshiba laptop through mini PCIe slot.

What are you using exactly to extend your M.2/ngff slot to mpcie? Did you manipulate bios whitelist?
