DFI NF4 Ultra-D video issue

My roommate just got his NF4 Ultra D and put everything together. Here are his specs:

DFI Lanparty UT NF4 Ultra D
939 3200+
2x512 Crucial Ballistix PC3200
XFX 6800 GT dual DVI
Samsung 710T
Super Flower/TTGI TT-550 Link

He's also using a 20 to 24 pin converter.

Anyway, after he clears the CMOS, he is able to get a video signal, only 1 LED lights up and you can only hear one beep. Once he restarts it, the same thing happens with beeps and lights, except he gets no video signal.

Here's what I've done so far, without success:
Put only one memory stick in Slot 2.
Switched memory sticks.
Switched PCIE slots.
Power connection on video card off and on.
Disconnected all unnecessary devices.
Switched monitors with me (I have the same exact model)
Switched DVI cables.
Switched to a 24 pin OCZ Modstream
Updated to BETA BIOS

Here is what DOES work:
Using a DVI/Analog converter and using the analog connection, though this obviously is not optimal.
Switched to a 6600GT (not either of ours)

I hope one of you guys can help us out. I'm really at a loss to what it could be.

EDIT: Oddly enough, it seems to restart just find so long as he doesn't let the display go into standby mode. Might be a video/monitor issue after all.
 
Did he try 2 different molex plugs from seperate wire runs ?

I had a similar issue, I didn't get any video till the desktop displayed when I had all 4 hd's plugged in.

Regards,
Jose
 
He actually only has one PCI-E power connector.

Also, it looks like it works fine so long as he shuts off the monitor before he turns off the computer. Looks to be more a video card/monitor issure than anything else. Weird stuff.
 
The fact that you switched to a different video card got it to sorta work, would lead me to believe there is a problem with the video card.
Or your refresh rate is out of sync.

I've seen this before and its usually a power problem or video card problem.

I would take the board out of the case and run it that way with no other components in it.
If you can see the bios screen, then you are good to go.

Do plug in the two extra power connection on the motherboard. This is very important. So you have 4 power plugs into the motherboard. The ATX, square 4pin, and both straight 4pins. DO NOT USE A 20-24pin ADAPTER.

Why is this important?

Can you link to some online info that explains the purpose of the extra power connectors [FDD-type/HDD-type] that are mounted directly to the PCB?
 
I found the information on the extra connectors. The text posted below is copied from a .pdf file available on DFI's web site.

"The HDD-type and FDD-type power connectors are additional power connectors. If you are using two graphics cards, we recommend that you plug power cables from your power supply unit into the two 5V/12V power connectors. This will provide more stability to the entire system. The system board will still work even if the additional power connectors are not connected."
