Hi, i have a problem with my egpu an i hope someone can help me with it. I have a lenovo x230t with an nvidia gtx 670. I conecctet them with a PE4L V2.1b with Expresscard and an 550Watt beQuiet power supply. This config runs without any problems for about a year. Here and there some restarts and hotplugs if it doesent start at once but it worked 99% of the time. But since a few weeks it doesn't work anymore. If i plug in the epxresscard before i start the laptop, between the boot and windows or with windows already running: the cpu usage get extremly high, Service Host: Local system (network restricted) and System Interrupts, eat the most usage and also windows stutters extremly, the mice pauses it movement every 1-2 seconds and so on. I tried a lot to solve this but nothing helped: i set up a clean windows installation a few times with just the needed drivers installed, i reduced the RAM from 8gb to 4gb, checked the gpu in another computer where it worked without any problems and also deletet the iGPU drivers. When it worked the sequence was to start the egpu, plug it in, start the laptop than, if it worked, the laptop turned off automatically but in 3-4 seconds turned on again and it worked. Now when he turns off automatically it seems that he is in some kind of endless loop and the display remains dark. This or the previous mentioned stutters. Also the Laptop doesn't recognize the eGPU in the device manager only the iGPU is visible. If someone has an idea what I can do to get it working I would be very grateful.
