Question Laptop doesn’t recognize external Graphics Card

Hey guys, what’s up?

So, I have a laptop Toshiba Satellite L755 with the following specifications:
CPU: Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz
RAM: 8GB (it came with 4GB, I added 4GB more)
64-bit Operating System, x64-based processor
Video: NVIDIA GeForce GT 525M
Windows 10 Home

I bought an adapter Mini PCI-E v8.0 Exp GDC, an MSI graphics card GeForce GTX 970 Gaming 4G and a power supply Euro Tech Silent Pro 580w.

I took out my Wi-Fi card from inside of my laptop and I putted the adapter’s cable there just as shown in the instructions. All necessary connections between adapter, graphics card and power supply are made as indicated.

What happens is:

a) If the pc cable (the one that I putted in the Wi-Fi slot, that connects to the adapter) is connected to the adapter when I turn on the computer the vents of the graphics card and power supply only turn around once, they don’t continue running, and the laptop screen stays black. The screen stays black while the pc continues on, nothing happens, which I end up turning it off on the bottom.

b) If the pc is on and I connect the cable to the adapter: the graphics card and power supply start working. Both vents keep on rolling and the adapter’s lights and graphics card lights turn on and keep on. I stayed with my laptop on all afternoon and they kept on working.

The thing is. My laptop doesn’t recognize the new graphics card. Everything is working but the laptop doesn’t recognize any of these 3 items. If I go to the Device Manager and then into the Display Adapters, it only shows the graphic card that I have in my laptop, nothing else. From what I saw in Youtube and from several sites, it should show something like ‘Microsoft Basic Display Adapter’ or ‘Stantard VGA Graphics Adapter’ or something like that so I can install the version of Nvidia of the new graphics card.

I saw in some sites that I should deactivate or change something in the BIOS regarding the Graphics Card or the PCI or the PXE Boot to LAN but my BIOS is super basic, I have none of these options.

I don’t know if there’s a way to change my BIOS into advanced mode or if there’s a way to make my pc recognize the new graphics card without touching the BIOS. I’ve seen so many videos and sites and I can’t find out what’s wrong.

Also, I have all my drivers up to date (I use Driver Booster 7 and also Driver Easy, all good). My Windows is up to date as well. I have Avast and Advanced System Care, so everything is in order. Also, the laptop was formatted 2 months ago. I’ve played Tomb Raider (2013) with my internal graphics card and it runs pretty great. With an Xbox controller and everything. I love Tomb Raider so I bought this new graphics card because I so want to play the Rise and the Shadows!!

If anyone had this problem or knows how I can fix it, pleaseeeeee tell meeeee! I can’t wait no more to play these beautiful games! It’s so stressful when you can’t fix something, argh! If you need any more information that may help you understand this situation, screenshots or something, just tell me.

Thank you very much for your time. Hope to hear from you soon :)

Best wishes,
