Hello . I need help connecting and configuring eGPU. The configuration of my laptop : - Lenovo b570 - Core i5-2450m - GeForce 410m - Intel HD Graphics 3000 - 6 gb RAM - Windows 7 Ultimate x64 I want to connect : - PE4C-PM100C V2.1 - Gigabyte AMD Radeon HD7870 - FSP 400W When I connect the card to the laptop and turn it , then run the video card , but Windows does not detect a new device. Tell me , what do I do ? Tried to delete all video drivers . Even cut off the discrete graphics card in the BIOS - did not help . I use a translator from Google, because I am from Belarus , so sorry if something is not clear.
