Re: r540 samsung

what type of connector do you got?
usually its cable or direct to motherboard.
when its with cable you got no power to motherboard.

Re: r540 samsung

I seem to recall that this model has a nec/tokin capacitor on the GPU, that may be the fault. Can you post some pictures of the mainboard? The capacitors will be on the back of the board (the side opposed to the CPU socket and GPU).

No, as they degrade quite a bit when being soldered thru normal methods. You'll have the same problem soon. Just use regular tantalum caps.
