Question : Problem: Dump after Dump after Dump

Hey everyone...

I'm hoping that some of you can help me determine what is causing my dumps )o: before I put anymore $$$ into this system.  

History:
I had an ASUS P5ND2-SLi Deluxe that hit the skids last month...I sent it back to ASUS and they don't have that model anymore because it was so worthless...so they upgraded me to a "better" board.  

Current Config:
ASUS P5N32-SLi Deluxe
Pentium D 830 @ 3Ghz
2 BFG 6800GT OCs PCIe
2 Gig Corsair TWIN2X1024A-6400 (512 x 4)
2 WD2500KS SATA (250Gig)
1 Maxtor ATA (40Gig)
1 NEC DVD-RW
1 Sony DVD-RW
1 Antec TruePower TII 550W PSU ver. 1  (only 4 ATX12V pins where the new mobo has an 8 pin plug...the new TII has the 8 pin)

So I'm typing right now on the this computer but...like it did 10 minutes ago...it crashed and gave me another dump.  When I first got the board last week from ASUS, I reinstalled everything that I had before on the computer and it looked okay.  Then I tried to play Unreal Tournament 2004 and Quake 4 and in SLi the games would freeze the computer before I could start to play...and if I played it with only 1 video card...I would get dumps.  So I checked the dumps and some said that it was caused by memory modules and some said it was due to different drivers.

So instead of tracking down all of those drivers...I reinstalled XP...this time, with only Nforce Chipset drivers, GeForce Drivers, Windows Debugger, and drivers for 1 NIC.  Then I installed Unreal Tournament 2004 again and I was able to play in SLi mode in the game, but I'm still getting dumps...sometimes without any load on the cards or CPU...now it is a consistant dump.  Everytime I crash now It states:

Probably caused by : ntkrnlmp.exe ( nt!ObpCloseHandleTableEntry+39 )
Followup: MachineOwner

I know that the ntkrnlmp.exe has to do with NVidia...but is it the Chipset or the Video Cards?  Could it be my Corsair memory isn't supported?  or might it be, even though an ASUS tech said it was okay, that my PSU is only using a 4 pin ATX12V connection instead of the 8 pin that the motherboard was designed for?  The tech said it was okay, but my experience with ASUS has taught me that I have to teach them the solution.

I don't want to dump anymore $$$ into the system because it is already an expensive box that has only been around since last October...so far I've had 3 mobo's from ASUS and 1 Video card replacement from BFG.  I'm A+, N+, CCNA, and MCSA certified and this crashing has me at the end of my rope.  Maybe if I had the time to spare I could find the solution, but I need a stable machine ASAP...and I'm looking to everyone out there to help me pinpoint this faulty config.  I'm leaning toward the Corsair modules or the PSU...but before I change anything I need some reassuring certainty from people that know their stuff.

Thanks a ton to everyone in advance.... (o:
