Can you hear the HD spinning for 1-2 minutes as it normally does to boot into Windows? How about RDC/VNC once its booted (assuming it does)?

Can you tell if you're making it into windows (or if the rig isn't booting past the BIOS)? If its the latter, I'm guessing a riser or slot isn't working. Are any of the risers powered? You might be overloading the mobo if they're unpowered.

I'll tip the person who solves this problem

I have one rig with a

gigabyte ud5 x79
evga 1300 watt psu
3x radeon 290

and I have one radeon 270x I want to use.

Currently I am using the usb3 pcie x1 risers for 2 of the 3 radeons and one radeon is in the pcie x16.
If I connect the radeon 270x via another pcie x1 usb3 riser the pc turns on but nothing shows up on the screen



I'm guessing you're using a linux based OS? I frequently get no video feed when I go from 1 GPU to 2+, BAMT, Xubuntu, etc. I went nuts trying to figure out why and simply gave up. I ended up installing SSH/RDC and after 1 GPU, I connect to the rig remotely to do everything else. Not sure why this happens, but every rig I've setup had the same issue.
