First thing I think of when I read your problem is to check for a bios update and install, for the mainboard. Let us know if you did this and/or if it helped. We may have further suggestions if not. Good luck.

Hi

I had exactly the same issue with 2 x 285 and SLI. There are a number of threads within the forum with possible and I tried most of them but in the end gave up and removed one of the cards.

I assume you tried installing the drivers with a single card and then re-added the second one?

If you use hybrid sli you have to connect the monitor to the motherboard on-board video out. Its probably the reason you are not getting any picture. You can disable hybrid sli in the bios but I recommend you use it as it can save some good power and even improve performance.

If all looks good and it still seems like a windows problem, try this;

-Install a driver cleaner utility such as drivercleaner.net. This is a nice free one; Guru3D - Driver Sweeper (Setup) download from Guru3D.com
-disable AV
-Uninstall all nVidia drivers through the windows control panel (physx too)
-restart and boot into safe mode (F8)
-run the cleaner and select nvidia cleaning only!
-restart
-disable AV
-Install the latest drivers from nvidia by right-clicking and running as an administrator. NVIDIA Driver Downloads - Advanced Search
-restart

Yes, I tried that. The problem I had was after exiting BF2142, one of 2 things happened, either:

The resolution remained very low as set by the game, or
The background went black until rebooted.

As soon as I removed one card this was resolved.
