I tried to power it on, and I get a long beep. The screen says that I did not plug in the power cable for the graphics card. I checked it and its on. I unplug it and reattached it. Power it back up and still having the same problem. I have a temp probe for the GPU, so I thought that might cause the block to not seat properly. I took it out and reseat the block and still the same thing. I'm out of idea. Anyone got a clue? This is on a IC7 Max3, x800 Pro, and Twinplex Pro GPU.
