Monitor asleep

I finished building my new rig, and everything works fine, except that when I turn on the computer, the monitor does not turn on.

I have a Hyundai L90D+. It works just fine with my old computer (that's what I am typing with now).

I cannot even manually turn on the monitor. The damn thing just wouldn't turn on.

Everything else runs fine, because I can hear the OS loading and the audio feedback is fine.

Every ten boots, the monitor would turn on.

I changed all sorts of settings on BIOS, but nothing works.

Any ideas?

The strangest thing is that the problem is intermittent.

If I press the reset button, sometimes the monitor would turn on, but most of the times not.

What the heck?

EVGA support thinks it may be a defective gfx card.

It's rare that a company would own up to its own faulty component.

I thought they would blame the mobo or the monitor.
