It's certainly a real strange one, yeah if there was no display at all through the gpu then of course dead card, but it's so strange its sending a signal through the hdmi.
I must admit I am stumped, my last recommendation (if possible) would be to try the card in another pc and also try a different card in your pc.
That will pretty much give a 100% diagnosis of the issue.
Sorry I can't help any further.
