I have a brand new home built machine with a new Gigabyte Z68 Motherboard. I had only 1 6 pin plug in the graphics card...i plugged the other one in and all of a sudden I get no signal anymore. I dont even get a signal with the on board graphics. I have no idea what to do. as soon as I plug both in and reboot...no signal. Take one plug out and the plug in the hdmi in the motherboard I get a signal. WTH?
Any help...thanks. Also I edited the bios to show the right pCI express slot for display.
bottom line is when I install and hook up the graphics card there is no screen in the new computer. On the old computer it worked perfectly. So there is something going on here in the new build. I just dont know what it is.
