well you located the area of the short,
but the black caps re probably not the cause.
it's probably a ceramic cap near them.
if you had an esr / low ohms meter you could narrow it down like that, but as it is you need to make a list of all shorted ceramics etc and then try lifting them one by one.
i'v done this a few times myself, so i know it's a long task.
btw, just hope it's not the actual gpu or ram!

When I had the GPU and RAM off I did a quick resistance check, They seem to be ok
Ok MOST ceramic caps are giving less than 1ohm resistance in cct, out of circuit they are not allowing continuity at all (on ones I have pulled) if I put my probes to both pads from 1 cap it is giving me very little resistance. This normal?
Still it seems odd to me that BOTH pads off the cap will allow continuity when nothing is bridging them. No doubt my logic is flawed with series vs parallel ccts
So when will I know when I have got it... Will removing it from cct change my reading in the cct itself or do I have to test every bloody little cap on this board out of cct?! Only around 200 of the f'ers!
you will know when it shows less than 1 ohm off the board.
at that point, you will probably find that you dont see a short across the pads on the board anymore.
