New build Problem (DFI, 6800, AMD 3500+) - No Display

[nanahachi02]

So I just put together a new computer rig, and for the past 24 hrs I've been dealing with "new computer" problems. I'm using all brand-new components:

Antec P180 case (black, SPCR version)
AMD 3500+
DFI LanParty UT nF4 UltraD mobo
Leadtek GeForce PX6800TDH (256mb) - PCIe
pqi TURBO 1GB DDR SDRAM Unbuffered DDR 500 (PC 4000) Dual Channel Memory
WD Raptor 74gb
Seasonic S12-500 PSU
Scythe Ninja Heatsink + 120mm Nexus fan

When I turn the power on, the case fans will spin, the Northbridge fan on the mobo will spin, the HDD seems to be on. However, nothing is showing up on my monitor (having tried both the DVI and VGA outputs, and trying 2 different monitors). The screen stays black, and the LED on the monitors stay amber, indicating that they are still on "stand by" b/c they are not getting a signal.

I have tried various RAM configurations/placements, I have tried booting with only the vid card plugged into the mobo and the HDD & optical drives disconnected, etc... nada.

Does anyone have any experience with this DFI mobo and Geforce PCIe video cards?

Another problem(?) seems to be that the computer will power on (fans spinning...) when only the 24 pin connector is plugged into the mobo from the PSU, but will not start up AT ALL when both the 24pin AND the additional 4 pin connector (square-shaped arrangment, NOT in a line like Molex) are plugged in
Thus, I have left it so that only the 24pin power line is plugged in. This seems weird...

I've been searching around here and online, but if I've missed some obvious threads/links, please feel free to post. Any help will be greatly appreciated!

did you connect the gfx card to the power supply? its proboly a 6 pin pci-express connector.

actually, I was shocked to see NO power connections on the gfx card, neither 6pin nor 4pin...

the heatsink on the 6800 is spinning, however.

I had that problem too (with a different motherboard). Try resetting the BIOS. (remove all connections the computer has to the outside world, monitors, network, mouse, power outlet, anything, and then remove the BIOS battery and leave it out for about 10-15 minutes, then put it back in and boot the computer)

thanks neal, will check that out!!

Crescent, I will do that now and see if that works. I just read something similar just a moment ago about taking the battery out.

again, thanks for your replies, guys. new computer pains just suck.
