So i have a dell inspiron 3656 and it has a processor with intergreted graphics. Everytime i play games my processor is at 100 percent and my graphics card is at like 20 percent. I do not know how to enable my graphics card which is the amd r9 360. I have my monitor cord pliged into the middle-bottom port which i think is the motherboard. There is a top one which i am pretty sure is the graphics card but when i plugged my cord in a screen came up saying it is disabled. Please help as my graphics card would boost my pc perfomance.
