Ok, to make a long story short, I've checked and double checked everything you've said.
The hard drive led and the disk drive led turn on like they're supposed to. When I try booting up the POST code led's show two dash marks. (like this: "- -")
Still no output on the monitor.
Both ends of my SATA cables seem to be locking ends.
I have the RAM in the blue connectors.
When I installed the board, everything lined up pretty neatly.
The power is connected in all three plugs. The manual was on the disk so pretty much everything you've said I already did.
My video card has two monitor outputs. Should I somehow be using them both?
The connectors for the power led are labeled "+" and "-" and I had them right before. The wires on the hard drive led connector are red and white. I'm assuming red is positive. And since the power and reset switch have no polarity I'm certain they're in the right place.
The tower assembly looks and sounds fine to me. Just, not seeing anything displayed. Can't be the monitor because I've tried it with three different ones. Considering I've spent nearly $1000 on all these parts, this is just a little bit more than just frustrating.
