I connected up a Gigabyte GA-8GVMT 4 Motherboard, when I turn on pc the green light on monitor turns orange, then I saw there where no jumpers set, can you please tell me which must be set and the settings.
Eh? Well, it sounds like you're getting no video signal. My guess is that you've got the monitor plugged into a video card, but the onboard graphics on the motherboard are still enabled. That can be fixed by just turning them off in the BIOS; the video card should work then.
Or, if you're not using a video card, you could have the onboard graphics disabled in the BIOS. Doing a CMOS clear by removing the battery should fix that.
Of course, these are just guesses, but without more information, that's all anyone can do.
