Windows + SLI problem

[Blew]

I have two 670's in sli and for some reason windows will only display when my monitor is plugged into then 2nd gpu, but when i try to get into my bios i have to plug my monitor in my 1st gpu. I have tried taking out the second gpu and using only the first and it works fine in bios/windows, but when i put the second one in again it goes back to how it was before.

 

Is there any way to make my 1st gpu the default for windows? Thanks.

I believe you can in the Nvidia control panel

I fixed it, thanks. For anyone with the same problem: I had to disable sli, plug my second monitor into the first gpu, then hit activate all displays in nvidia's control panel. Then i just plugged my first monitor into the first gpu and it worked.
