msi GE70 2QE not open with gpu

[Anethra]

motherboard model ms-17591 ver1.0.

When I start the computer with the coils of the video card installed, the adapter falls into an instantaneous short circuit. but when I remove the coils of the video card, the computer turns on and the image appears. I changed gpu supply (uP1642) and gpu (N16P-GX-A2) but there was no change.

up1642
1 BOOTT1 = 4.44v
2 UGATE1 = 0.02V
3 EN = 3.2V
4 PSI = 3.3V
5 VID = 1.5V
6 REFADJ = 0.99V
7 REFIN = 0.89V
8 VREF = 2.0V
9 TON = 0V
10 FBRTN = 0V
11 FB =0.06
12 COMP = 0V
13 ISEN3 = 0V
14 ISEN2 =0V
15 ISEN1 = 4.4V
16 PGOOD = 0V
17 UGATE2 = 0.02V
18 BOOT2 = 4.45V
19 PHASE2 = 0.02
20 LGATE2 = 0V
21 PVCC = 5V
22 PWM3 = SHORT
23 LGATE1 = 0V
24 PHASE1 = 0.01V

These measurements are without coil. I can't measure with coils because computer won't turn on. I'm waiting for your help

u have probably shorted mosfet on one of gpu phases. check resitance

Re: msi GE70 2QE not open with gpu

As you said, one of the mosfets is faulty. But even though I change it, nothing changes.
