I just got an msi geforece gtx 660 (non ti) twin frozer oc edition, and along with that, a 500w psu. I put the psu in the pc, run it, it worked like a charm. Then I the grahpics card, by plugging everything in, i know everything is correct, i used a vga-dvi adapter to do so, my monitor only supports vga, but when my graphics card is in my pc, everything runs, fans spin, etc, but there is no display on the monitor, so i cant install drivers or anything, so what do i do?
