Need help. Gtx 680 problem

[Mtl_oryza]

Hi, i recently built a brand new custom computer.

Intel 3770 ivy bridge
Asus P8Z77 SW
EVGA GTX 680 SC
Corsair Dominator 32gig of ram
Thermaltake 1000w Power supply
Dell u2711 monitor

I installed windows 7, everything works ok. I install the windows update and everything but as soon as i install the nvidia drivers and perform a reboot. The minute the windows splash logo pops out, my monitor would go into powersave mode. I tried rebooting like 6 times always goes into powersave mode at the exact same spot. I would then go into safe mode and cleansweep the nvidia driver and do a reboot and the pc would work normally again. I even try the new beta driver and same problem all over again. As for cables, i tried hdmi, dvi and displayport all the same results. Any advice is appreciated. Please help.

1. update your bios through a usb key
2. have you connected two 6-pin power connectors to your cards?
3. use the top PCIe slot?
4. disable your onboard GPU through the bois
5. connect to dvi-i output on your card and monitor

I am seeing the exact same symptoms on a system which I am trying to get up and running with Win7-64bit SP1.

The system specs follow:

BOARD: SuperMicro H8DG6-F
CPU: 2x Opteron 6274
CPU COOLER: 2x Noctua NH-U9DO A3
RAM: Kingston ECC, 128GB
GPU: 2x Zotac GTX 680 2GB
HDD: Intel SSD 520 Series, 120GB
ENCLOSURE: Lian Li PC-A71F
PSU: Corsair AX1200W

My system seems to be functioning properly in Xubuntu 12.04 with proprietary nvidia drivers but I am seing the same reboot symptoms in Windows 7. I will follow this thread with great curiosity!

I will also attempt the suggestions from redeemer.

Be sure to use the latest 301.42 WHQL drivers off the Nvidia website and select the "Clean Install" option.

I just tossed one of the Zotac GTX 680 GPUs into another machine.
I will install windows and see if the card works there.

I installed Win7 64-bit and used the 301.42 WHQL driver in a HP Pavillion Model vs167aa-uuw. It worked just fine, no reboot after the windows logo.

I even tried running 3DMark, it severely strained the PSU in this small machine but ran with smashing graphics.

So the question is:
What does my system have in common with Mtl_oryza's which causes this reboot issue?
