HI folks, looking for a bit of help here. I've just installed 2 MSI GTX 580 Lightning EXtremes into my rig but I am not gettng and display signal to my monitor. Now I didnt uninstall the previous GPU's drivers because I didnt think I'd have to because it too was a 580 just a referance design. I've tried HDMI and DVI and also without them connected with the SLI bridge. Any thoughts??? Thanks very much in advance.
 
Try uninstalling and re-installing the drivers.

Have you tried just installing one card at a time?

Have you made sure all the power cables are connected?
 
I had same problem with my 480s. You don't need to reinstall drivers. For some reason I found I had to put it in the top left DVI slot (looking at the back of the pc face on) and then restart the pc. After that it works fine. Turning the pc on and plugging it in gave me no signal. Strange I know. Happened both times I've set up my sli.
