bfg 6800gt pci-e lockup HELP!

[protoman89]

hey.. i just ordered a new system in parts, here are the specs..

Athlon 64bit 939 90nm 3500
msi nforce4 platinum with sli
1gb Patriot XBL PC3200
74gb WD Raptor 10krpm HD
2 80gb WD 7200rpm HD's
Plextor PX-716a DVD-RW
BFG 6800gt PCI-E 256mb OCed by manufactoring to 370/1000
Nforce LAN integrated
SB Live integrated
Dell 2005FPW 20.1 inch wide aspect LCD
Klipsch Promedia 4.2 Speakers
Thermaltake Soprano Case
Thermaltake 430W PSU with dual bearing fans

OK... here's my story..
EVERYtime i play Far Cry, Raven Shield or Run Aquamark benchmark my system lockup
after loading the game.. i havent tryed any other game, but ive tryed a lot of things..
Updated MOBO bios, video drivers, Mobo chipset drives, Disconnected some HD's and Fans in case it was 2 much for the PSU, even reinstalled windows in order to change the video card's IRQ since it was running in IRQ 19.. Nothing helped..
Disabled Fastwrites or any kind of overclock in the system or the card.
im not running sli, only this Video Card.

in aquamark itll load and run for 1 secong and itll crash.
Ive tryed disabling sound in case it was a sound issue, Itll crash the same way.
well, the guys over at BFG were really nice, and we tryed possibly all the things possible and nothing helps..... the tech suport guy told me to RMA but i just got this system built together and i just find it difficult that the card came busted... but any advices are appreciated. Ill RMA if nothing helps in a few days.

btw, the tech support for BFG parts and Monarch Computers was incredibly good, we just didnt find a nice solution.

I havent Oc'd anything cause im new to it and i dont wanna break anything.

thankz in advance.

Maybe your 430W powersupply is having trouble with the 6800GT and the winchester CPU? have you tried disconnecting non-essential peripeherials ( CD-ROM drives, one of the two hard drives), disabling non-essential builtin devices and settings in the BIOS (IEEE1394, LAN, Sound, USB ports, serial ports, parallel ports, disabling bios caching), and unclocking your CPU and/or video card? What are your temps like for your CPU and GPU? I would also run memtest86+ and prime95 to make sure your CPU and memory are working fine. After that, download one of the demos from nvidia.com and see if your system works oK with that.

Well, ive tryed that already, and in BDG i called and they checked that out and told me that th ePSU is fine, they ran some app they have to calculate how much wattage im using.
Im downloading the apps u r talkin about right now 2 check that out. The Video card was runnning around 70C idle, i think but they told me over at BFG that they run at that temp.

im gonna check on the ram applications you r talking about now, thankz for the help.
