Good Evening,
 
I have a EVGA 580 GTX SLI set-up in 2D surround (no 3D).  These are the 1.5 gb models.
I have had a 2D Surround set-up for this last year and it has been working great until tonight.  My set-up was working fine, and I went up to make some dinner.  When I came back down I noticed the display driver error (not responding) starting to periodically appear.  The system would restart the driver then be "ok".
 
OK until I ran something.  If I ran a game or even windows media center the driver error came up or it crashed the game.  Just sitting at the desktop it seems ok.
 
On a couple of occasions, I received the following pop-up:
"Nvidia OpenGL Driver
Driver lost connection with the display driver due to exceeding windows time-out limit and is unable to continue.
The application must close.
Error Code: 7"
 
I had been using the the 285.62 drivers and they had been working for me until tonight.  I tried a clean install of the newer beta drivers (285.79) and the same issues continue.
 
I have not made any changes to my system recently.  My system specs are in my signature.  Just to clarify I am running a Dell 730x XPS computer with a 1000w power supply plus a supplemental X5 booster.
 
Temps for both the video cards and system appear normal.
 
Any thoughts or ideas?
 
Thanks

Well, I think I figured out the issue.  It seems the flexiable SLI bridge was not firmly seated on the cards.  I am guessing that the tension in the flexiable bridge caused them to work out far enough to create thge issues I was having.  Perhaps need to look into a hard bridge.
 
If I order a 3 way one will it work with 2 way SLI?
 
Thanks
