All the major components are new
Core i3 2120
gigabyte h61ma-d2v motherboard
8 gb ram
2gb 660 msi twin frozr
I noticed the 660 has 2 blue dvi ports which ive never seen before and don't have a matching cable. we tried a normal dvi cable and we didn't get a signal, we also tried it in the mobo's white dvi port and it still didn't work. we do get a signal though if we remove the graphics card and use the mobo's vga port.
Also it works fine if we use his old graphics card and the dvi cable.
So I suspect its a problem with the graphics card. Any other ideas?
