I just bought the msi gtx 650 1 gb video card and when i put it in my mobo and start the pc, there is no video signal through the dvi port. When i took it to the service centre, they put it in a newer mobo and the video card worked. What shall i do now ? By the way, i have i7 920 @ 2.66 mhz, intel dx58s0 mobo, 3 gb ddr3 ram, acer al 1716 17" analog monitor.
