I had a dud card delivered to me before but your problem sounds strange. The card has never posted at all?

Try removing motherboard battery for a bit (about 5 minutes) to reset the bios. Will at least rule out some problems.

Also, why/how do you have 18GB of ram? Just curious as never seen that number before. I would try to post with minimum ram also.

does your motherboard by any chance turn off system fans when temperatures are low to reduce noise? try running a stress test, but make sure to monitor the temps and stop the test it the fan doesnt spin up

run some tests make sure the power connectors haven't come out slightly on both the cpu fan and gpu fan u might be able to see it behind the fan block on the gpu normaly at the end by the power connectors
