I'm not good at explaining this completely but my Dell Optiplex 7010 isn't detecting my GT 610 I recently installed. The only thing I see in device manager is my Integrated Graphics adapter.

I have tried upgrading the BIOS but that didn't fix it.

I have tried several other GPU's I had laying around but the system didn't detect those either.

The GPU is getting power though. 

Any help would be appreciated!
