So basicly everything was right and then one day my graphics card didn't want to display anything on monitor.I don't know what to do , both cables are in and it's connected to motherboard perfectly fine. It's working but PC can't recognize it. I tried to change settings in BIOS but there is no PCI-Express Graphics tad.I'm using windows 10 (I just installed it ).
Specifications of my Pc :
Intel(R) Core(TM) i7-4790
16 GB Ram
Graphics card : Nvidia Geforce GTX 970
