ok thanks for your analyze and advices.
i will first check the other rails to be sure.

I just had a look what is Mats / mods, ok will try that also and let you know.

thank you....

Ok sorry I understand, just came back home.

FBVDDQ is 33 ohms(probably not a short then)
NVVDD is 0.4 ohms

I check my multimeter measurement cables and they are 0.2 ohms themselves....

Ok sorry it's maybe a bit confuse. Just starting to learn, so i am throwing what i'm finding until i can know enough and connect the data together.

So starting again from Zero.

MSI GL75 9Se have an additionnal Nvidia RTX 2060 GPU.
This GPU is not working.
Using GPU-z we can't see any BIOS or Clock frequency. But the GPU is recognized.

sorry made a mistake "the short still on the line but there is NO short at the mosftet output".

thanks to guide me....

I made some test yesterday night, board on the bench with no power supply on it.

I found some short on :
_ FB VDDQ
_ NVVDD

All the caps of these 2 lines are on short.

From what i understand, that seems to be 2 high power supplies rails for the GPU and the Rams, right ?

I didn't found any short on the 1V8 line.

So what i did is to remove the choke 4, 5, 6 (on NVVDD line) to separate the mosfets from the power line. the short still on the line but there is short at the mosftet output.
I also removed the chock...

Hello guys.

I own an MSI GL75 (i7)
Motherboard : 17E51
GPU : Nvidia 2060 RTX

I spent weeks to install and clean the drivers but still have an code 43 and the Nvidia GPU not working.
When using the GPU-z the GPU is recognized but there is no clock frequency.
Seems the problem is from the hardware.

What do you advice me to check ?

Thanks
