    I bought a "broken" Notebook P670RS with not fully working GTX 1070. Actually only the integrated Intel GPU is working. In the device manager there is a yellow ! sign with Error 43. GPU-Z showing not all informations (sensors tab is almost empty).
    When I try to use only the 1070 (activate Option inside BIOS) Windows is starting with really weird graphic glitches/errors and the same error 43. GPU-Z showing almost the same information but now I can see the VBIOS Version. In this state I cannot do anything because windows seems to load safe state driver?

    Now I dont now how to fix the problem. I can open the laptop and try to check die GPU somehow? Try to give heat to the GPU chip (Hot air). The GPU seems not totally dead because Windows detect it.

    MB Series: P65_67RSRP
    BIOS Version: 1.05.07
    KBC/EC Firmware Revision: 1.05.05

    VBIOS Revision: 86.04.2A.00.10 (GPU-Z showing 86.04.2A.00.0E)
    Device ID: 10DE1BA1-15586B02
    Driver Version 30.0.14.9649 (ForceWare 496.49)
    Windows 10 64Bit

    The GPU is dead so maybe you could get a BGA repairer to put a new core on it? Could possibly be VRAM too depending on the exact issue.

    The curse of BGA strikes again. The GPU is defective. You will need a whole new system board or find a competent repair shop to desolder the 1070 die and solder in a new one (which could end up costing as much as a whole new system board).

    As a note it's quite easy for GPUs to somewhat "work" but have defective units so they can't render properly. They are so parallel that the front end and buses can be fine but a shader is dead.

    I fixed the gpu with a heatgun (+ temp sensor to control the heat ramp). I know that can work for maybe 1 month or years but actually it works :)

    Luckily then it was a reflow issue and not the die itself.

    You could kill the board doing that and have nothing is the issue.

    I agree but if you're going to or can't pay for an expensive repair or new system board, might as well give it a shot.

    If you can't afford that can you afford to brick it entirely?

    If you make it right/correct, then you have a good chance to NOT break your entire laptop. Use Kapton foil to shield everything around the GPU and use a temp sensor to control the heat, then its no big deal. Ok its little bit hard to remove the mainboard out of the notebook. And I paid 330€ for that broken notebook, whats the price for a GTX 1070 repair? I think more than 330€! And remember the GPU was already broken/faulty and only the Intel GPU works! Ok there is a chance that you make a short circuit somewhere below the gPU ... thats a risk.
