New Mining Rig Has A GPU Lagging.. Can't Figure It Out!! Help!

Good morning Steem!

Well, it's the second day of my mining rig being fully up and running. I've had a couple little petty issues that I've been working on but one that will NOT go away. I have 1 GPU lagging.

While the other 4 are mining their butts off, 1 GPU just wants to play around. I have reinstalled drivers, turned off the entire rig and reseated all connections, etc. When I reboot the rig, it goes from GPU#0 (the first GPU) to GPU#4 (the fifth GPU) and vice versa.

Unfortunately, I'm all out of ideas. Any Steemians out there that might be able to help me resolve my issue? Also this doesn't just happen with 1 miner, it happens with all different ones.
