I have now attached PSU, MOBO, RAM, CPU, its cooler and GC. If I turn it on, I get no BIOS when GC is attached. When I unplug it and put my HDMI cable in to the MOBO, BIOS shows up. Does that mean that it's malfunctioning or doesn't work at all? The fans do spin in the GC, though. My specs are in my signature.
Install GC. Have monitor attached to MB port. Start it up. Get a signal to the screen? Then go into the BIOS, turn off the internal video (MB) / switch to PCI-E video. Power down. Switch monitor to the GC port. Power up. Screen signel now?
Some cables come a little loose if they're at angles. Occasionally my PC will shut down because the mobo power cable is finicky when it's angled. I'm going back to EVGA with my next board since their mobo power cable is at 90 degrees rather than 180 from the motherboard.
