Hi. I'm new to the forum and eGPU. I bought PE4H-EC2C ver. 2.4 from amazon Amazon.com: PE4H-EC2C (PCIe Passive adapter ver2.4 with EC2C ExpressCard): Computers & Accessories When I got it, I plugged a GTX 460 to it, powered the GPU and PE4H, and connected the expresscard to my laptop (Sony Vaio VGN-Z790DKX). At first, it recognized the board and the video card and tried to install drivers. Then in the middle of it, it says the board was "disconnected" and neither drivers installed. Next time I plugged it in, nothing happens, and I don't see anything on my device manager (not even a device with error 12). Anybody have any idea why? Do you think the board burned out or something? Thank you.
