Okay, I removed the 4th GPU and started the computer and as expected, it booted right up to Windows!
There is something definitely off when I install the 4th GPU; or actually, when I insert GPUs into the 1st and 3rd PCI-E slot. Could it be a power issue? I'm using 2 EVGA Power Boost modules for extra power to the PCI-E lanes since my motherboard doesn't have an extra molex connector.
