    Your only option then is to replace the motherboard yourself. It is doable (I fully opened my laptop without any hassle) but very expensive. You can get the motherboard from samsungparts.com.
    Maybe you can tell us more about when the error appears, what happens to the computer etc.?

    I'm wondering if anyone knows how to achieve 10,000 mW of power usage shown in battery bar and SW settings? The lowest I ever went was ~13,000 mW. No matter what i do, even go into power saving and silent mode, I can't achieve 10,000 mW like I've seen others report to achieve in the past. I have the touchscreen version, np770z5e. Because of my high power usage, I can never achieve even 6 hours even on a full charge, even when just browsing the web or typing a document.

    The challenge is to figure out what is using the power.

    BatteryInfoView (I prefer it to BatteryBar for instantaneous readout) shows system power drain and ThrottleStop shows the CPU package power consumption (see an example of those in my post here). The display backlight might need 1-2 W at minimum brightness (but a lot more at higher brightness - you can quickly observe the effect of changing brightness on system power drain by watching BatteryInfoView).

    One of the first things to check is whether the dGPU is powered down. I think (but I'm not certain) that HWiNFO will show this.

    Honestly motherboard replacement is probably not cost effective at this point. I know it's a bit hypocritical for me to say as I'm a guy that rebuilds 5+ year old gaming PCs for household decorations, but in this case I have to agree with popular opinion. Since the laptop has integrated graphics and isn't really sufficient as a gaming rig at this point anyway, you might as well just disable the dedicated and use your IGP instead. For some reason replacements parts for these cost more than just buying a used one in many cases. The 8870m is still a decent card, but not worth hundreds of dollars and a decent risk of cracking or breaking something during replacement.

    That being said, you may be lucky and your GPU isn't actually dead. Error code 43 is caused by the drivers crashing. This can sometimes be caused by hardware failure but is just as often a driver conflict. For example when WoW Cataclysm released, it had a bug where the new water effects would cause a crash almost identical to VRAM failure and as a result many people replaced their GPUs. Once the game was patched, problem was solved and those cards suddenly worked again.

    Also there have been several occasions where past GPUs I've owned would overheat or crash and the problem turned out to be either dried thermal paste that was cracking or a thermal pad that was sliding out of place. Once I repasted, the issue was resolved.

    So before you go nuts ordering new parts and tearing it apart, I would recommend doing a full driver removal and reinstall as described at the beginning of this thread. If that doesn't resolve it, maybe open it up and check the condition of the paste and/or thermal pads. If you are lucky, you won't have to put half or more of the value of your laptop back into it in parts.

    Bummer. Do you get the error every time you launch a 3D app, or after you've been using it a while?
