So I kinda updated my PC. I bought 4 gigs of ram, 1tb drive, and a Nivida Geforce GT 610 graphics card. It ran two days. Today when I came from town I wanted to turn on my pc the display didn't turn on. I plugged the display into my laptop it worked, I plugged in my old graphics card it didn't work. I have a Gigabyte GA-G31MX-S2 motherboard and it has a VGA controller, I plugged my cable there and it worked on normal resolutions, but when I checked device manager it didn't find my graphics card, only a VGA controller.
Can somebody help me? Can the motherboard not see the PCI-E port?
