HDTV/PC no longer recognize each other

Hi, I've been using my 42" Toshiba Regza as my primary monitor for the last 6 months. I recently upgraded almost my entire PC and now they won't communicate with each other. Here's a quick summary and my setup.

LCD will not display any signal coming from the computer (it will not even display the post... this means it's not a driver issue right?). My computer won't recognize the display even with force detection enabled. My TV won't recognize the computers signal and reads a constant "No Video Signal".

The Box:
MSI P45 Neo3-FR, Core 2 Duo E8400, 8800GTX, DVI => HDMI dual link connection, 4GB DDR667, 650W Antec Earthwatts, XP Home SP3

What I've tried (not in any order):
*Swapped CPUs
*Swapped Mobos
*Swapped Video Cards
*Swapped Cables
*Tried Different Video Drivers
*Reset TV settings
*Flashed Mobo Bios
*Swapped RAM
*Tried on all 3 HDMI Ports on the TV
*Tried both DVI outputs on the Video cards
*Booting with single & dual monitors

I've been terribly frustrated the last couple days trying to sort this out. I have pretty much reassembled my old computer with the exception of the power supply and they would still not recognize each other. Any help would be greatly appreciated. I'm sure there's key points that I forgot but any help you could give would be awesome! Thanks in advance.
