when you say verizon card, i am assuming you mean a network card.

WHen you said the monitors worked before, did you mean with the onboard video or with your new video card?

If they worked with the new video card, were they working before or after you put in the network card.

The reason i am asking this is that more than likely there is an IRQ conflict with the new video card and the new network card. You might want to also make sure that the onboard video is disabled in the BIOS.
