Hi I recently purchased a gtx 1060 3 gb graphics card and I’ve uninstalled my previous graphics card and installed the new one. There is light in the graphics card but no display on my monitor when I plug the cable from the monitor into the pc, I’ve tried dvi-d and HDMI and no luck. My psu is xfx pro550w. My graphics card requires an 8 pin but my psu has 6 pins with 2 pins you can attach. I don’t know what the problem is and I need help.
