Hello all, I am new in this area (eGPU) and have some issues. When I Google my problems, this forum pops out to me. After review some posts, I still cannot figure out my problems, so I decide to register on the site and ask my questions here. Those are my parts: Lenovo Thinkpad x230 with i7-3520M, 16GB RAM, Intel(R) HD Graphics 4000 EXP GDC BEAST, Expresscard EVGA 500 W1 80+, 500W Continuous Power, Power Supply Gigabyte GTX 960 Overclocked 4 GB GDDR5 Graphics Card GV-N960WF2OC-4GD My problems are: When I pluged in the Expresscard, the computer can catch the graphics card, and it told me to restart the computer if I want to use it. After I restarted the computer, it worked! The fans on the graphics card spun, and I can see the screen in the external monitor, and it showed me that I was using GTX 960 now. I tried to watch the movie, and it worked well. But the fans on the graphics card stopped spinning. I am not sure it is normal or not, but my computer still worked fine. HOWEVER, when I tried to play the video game, it worked at first. But after about half hour, it would suddenly shut down, then restart the computer. At this time the graphics card did not work, so I have to use the internal LCD. I was trying to re-start the graphics card, but it still did not work and it was a little warm. I have to wait for some time to use the graphics card and the whole kit again. Does anyone know how this happen? It worked for a long time for movie(at least 1.5hrs), but it only worked for 30min for game. I also tried to change in BIOS. Inside "POWER" I think there is "PCI Express Power management", and the default is "enable". I tried to change it into "disable", but the result is still the same. I tried this change because I thought this is referred to "Disable PCIe Power Saving", but I am not sure. Or does anyone know where should I change? I would very much appreciate your help in this case. Thank you in advance! Sammael
