Bad solder spots would have refluxed with the heat,
I will inspect it I got a 60-100x portable mag gadget with a led on it so you can trace anything visual with that, but I suspect if that would be the problem, it would be within the layers, looks like a 4 layer PCB.
the other thing is under the card, very hard to trace stuff live with touching and seeing a reaction on the screen, pressing the GPU makes changes, but I suspect it is due more to the pressure on the PCB than the GPU being not well connected; when I try to shear it sideways it doesn't apply the same kind of pressure to the board and I get 0 reaction.
Anyways if heat is the issue, then I suspect the capacitors right under the GPU on the other side of the PCB since in theory, this should be the second hottest place on the board when under load.
Thanks for the idea will look at it...
