Hello, Sorry is this is the wrong section I am new here Before I start I am connecting though my old wifi card slot. A PCI Mini I recently brought a Nvidia GTX 950 along with a EXP GDC GPU dock (Latest Version) and a 550w power supply plugged into the 6pin slot on the dock. I have had some issues with the setup, I have everything powered however, when I boot i get a black screen with some back light on my screen on the laptop and nothing happens. The monitor that is connected to the GPU has no signal. I have tried hot swapping straight after when the bios finished loading and the fan just spins really fast like a blow dryer. Also if I plug it in while windows is on nothing happens nor is the GPU detected. If i remove the GPU and the dock is left plug in it will boot up. I am currently running a fresh install of windows 7 with my Intel graphics drivers installed and my 840m is UNINSTALLED. Any solutions to making this GPU work? I tried the delay switch but i had no luck with it. Still gets stuck on a black screen. Specs: I5-4210U + Intergrated graphics Windows 7 Ultimate 64 bit Nvidia GT 840M (Uninstalled) Bios version 1.32 Z5WAH 8gb RAM Laptop model: ACER V3-572G Any help would be fantastic Thanks for your time P.S Can anyone tell my why some of the words I write hyperlink to ebay?
