Dell (Inspiron 15-7559) Nvidia 960M Code 43

[evgenyjp]

Hello,

I originally had a problem with this customers motherboard Nvidia GPU throwing a Code 43, I replaced the GPU today with a new one and still getting the error Code 43 in windows 10 and it's driving me insane. Usually replacing the GPU repairs this for years, but this is that hybrid graphics garbage that I despise.

Anyone have any ideas on what I may be overlooking on this repair? DAAM9AMB8D0 Rev: D board.

check its power with oscilloscope, the oscillator, and which actual PCI IDs you are getting from the chip (as there's a non-zero change you bought a remarked chip)

Thank you for reply !

powers seems good.

Any idea ?

Also I know, another people got same problem. Seems common issue for this model...

What's the power draw like? Bad caps, especially tantallums, can cause this too. And, of course, where did you source the chip?
