every time my computer comes out of sleep mode, or when it's first booted, it makes the "doodum" monitor detected noise about 7 times. I have 2 monitors hooked up to my win7 64 bit machine. One's connected via DVI, and one via display port. I think the DVI one is the culprit. My video card is Nvidia GeForce GTX 670 Any idea how i can stop it from doing this?
