SLI HELP - Just installed a 2nd ASUS GTX570 DCII and Nvidia CP is crashing!

[GprophetB]

Hello there! Hopefully someone can lend an idea since ive tried everything i can think of.

SPECS:

P8P67-Pro (with latest bios
i7 2600k
OCZ 1000 watt ZX PSU
ASUS ENGTX 570 DCII
ASUS ENGTX 570 DCII
8GB Corsair XMS 1600
Windows 7 ultimate
Drivers 280.26 also tried 275.33

PROBLEM:

Windows recognizes BOTH cards no problem in hardware manager and within Nvidia control panel. Upon opening Nvidia control panel and enabling SLI (leaving everything else the same no other changes). Once i enable SLI, nvidia control panel crashes, windows reverts to 800x600 and both the cards are disabled in hardware manager with the hardware code 38, which i believe is driver related.

WHAT I'VE TRIED:

-I've tried each card individually in both slots, works fine
-Motherboard bios is up to date
-Tried both slots on the mobo individually
-Tried re installing both sets of nvidia drivers
-ALL necessary power connectors are plugged in (1x8pin and 1x6 pin in EACH card)
-SLI bridge tried on both slots and i even tried a different bridge

All this with NO luck. Any ideas? Please? lol
