I woke up this morning to a computer with no display.
I could remote it with TeamViewer, but could get no video response.
I removed the GTX 970 and replaced it with a GTX 570.
Everything is working great now.
As I was removing the 970, I heard something rattling around inside of it.
That was rather strange and fired my curiosity.
I opened it up and a loose power inductor dropped out.
Below is a picture of the board minus the inductor.
(If the picture will attach)

The inductor apparently fried and got so hot it melted its own surface mount solder connections.
(Located in the red rectangle in the picture.)
The other inductor in the rectangle is not looking too good either.
My internet search discovered that this has been happening with some classes of NVIDIA based GPUs.
Some think that NVIDIA's manufacturing partners are cutting corners by under specing these components with cheaper ones.

The MOSFETS look OK visually, so just for fun I'd thought I play at replacing the two blown inductors, with a fire extinguisher handy, just to see if I can resurrect the card.
Finding the specs for these 220 nano henry inductors is proving difficult for me.
The package is about 10mm x 10mm x 4mm to fit the board.
But I'm having a hard time determining the amp rating. I'm assuming they are 10A.

Anyone know the specifics for these inductors and/or a possible source?
This is not critical. I'm just playing at fixing this card.
