I have a 5 year old AMD R7 250. My card won't always power the display then I have to switch the VGA cable to integrated graphics. One day it will power the display then the next day it won't. Also, when the dedicated graphics is connected then the integrated will make the monitor blank and vice versa. Thus forcing me to constantly switch the VGA cable almost every time I sit down to use my PC. I have reinstalled windows 7 even went from win 7 to win 10. I have installed the drivers from the AMD site also. Please Help!!!
