PrecastFlame Posted February 7, 2019 Share Posted February 7, 2019 (edited) Hi, I'm having problems trying to connect a GTX 750 Ti to my Lenovo T420 using the dock EXP GDC Beast (express card version). My laptop: Lenovo T420 RAM: 8GB DDR3 CPU: Intel Core i5 2520M GPU: Intel HD Graphics 3000 My problem is: if I plug the express card and I turn on the laptop it doesn't boot up and the screen becomes horrible, with coloured pixels and a sound like "bip-bip". If I try plugging the express card when the laptop is already turned on it sees the gpu, but if try installing the drivers I have to apply the modifies restarting the computer. I hope you understood my problem (I don't speak English very well). Please help me, It's making me crazy! EDIT: I didn't say that if I plug the express card when the pc is already turned on, in the device menager there is "Error 12" on the gtx 750 ti Edited February 7, 2019 by PrecastFlame Quote Link to comment Share on other sites More sharing options...
