I bought a gigabyte GeForce gtx 1050 ti, oc, windforce. Motherboard = P8B75-M Asus. Processor is i5. When instelling the graphics Card, I have 2 issues. 1) No power pin connector (maybe this Card Draws from the motherboard). 2) Black screen when turnong on pc. Only 1 monitor (led monitor 226vla philips). When putting bck old card, GeForce 650, the screen 'works' again.. any solutions?
