Recently bought a video card PX 570 4 GB. And from the moment the problems started with it, at first when I connected, there were problems, the screen was not shown. But I decided it. Now, the computer with this video card started to turn on longer, sometimes when you turn off the computer, the fans of the video card start spinning very quickly and the computer does not turn off, and sometimes the settings are reset. Not overclocked, did not do anything with it, the latest version of the drivers. And what could this be?
