I just bought a new graphics card and I put it in my pc and when I plugged the vga cable into it, it just was a black screen. So I hooked up to my regular vga spot and started my pc and went into device manager and looked at adapters and the only video card that popped up was my internal one. I tried to disable my internal and start it up but that didn't work either. Someone please help I really want this card to work.
