So I recently installed a 560 Ti in my system and decided to run an old 8800 GTS along side it for Physx.

Whenever the 8800 is physically present the system will go through the post screen, but before it gets to the windows loading screen (I'm running Win. 7 Professional) it reboots. Ad infinitum.

Strangely enough, I've used this card before for Physx in the same system in a hybrid setup (2x 4890s Crossfire + the 8800 for physx). And and all was fine. A few days prior to installing the 560 I, on a whim, tried to use the 8800 with the radeons for a physx game. And that's when this reboot problem initially started.

Now before any of the installs I used Driver Sweeper and deleted the temp files to ensure any driver remnants weren't present in the system. But the problem seems to occur even before any driver files are loaded. With ONLY the 2 radeons or ONLY the 560 present the system runs fine. With the 8800 physically in a slot...reboot loop.

Relevant System specs:
EVGA x58 SLI
Core i7 920 @ 3.6 GHz
EVGA 560 TI
EVGA 8800 GTS
Corsair HX1000

Any help would be appreciated.
