Hi, I have a problem with the Alienware m17x r3. Just when I disconnect the dedicated graphics card, the laptop works normally and when it is connected it turns on for one second and goes off. What may be the problem? Recently, I was able to fire a graphics card and discovery card in bios. Later, I tried to install the GPU drivers, but the error was "something like no hardware found." The next day the laptop would not turn on.
