I have one question. When I start my computer with additional graphics card, the screen does not start, there is a black screen, a fan of the graphics card runs at full speed. And when I turn on the monitor connected to my on-board (integrated) graphics card all looks normal. Does that necessarily mean that the graphics card is good for the garbage or it may be something related to the motherboard?
