GAH! need help with new 6600GT/MB combo

[Homerboy]

have a brand new MSI 6600GT PCI card. I THINK I have all the 6 different jumpers on the DFI in the correct spots (default) with all of them covering the bottom pins in the sets. Correct? The 6600GT has no power connector on it but I see the DFI has 2; an HDD type and a FDD-type. Which do I use both? If I power on with the 6600Gt in the bios is and splash screen is totally unreadable, as if its not getting enough power. even with EVERYTHING unplugged. PSU a new(er) Antech SL400 400W
