hp Pavilion X360 14-dh1017np freezes when loading Windows

[Kambi13]

Hi, today on the menu i've got an hp Pavilion X360 14-dh1017np that had it's main power rail shorted with 4 blown 10uf caps and one of the DrMos.
Replaced all, and now the laptop does power on, but when it starts to load Windows freezes within a few seconds.
CPU VCore has 0.931v in first Coil, 1,045 in 2nd coil and the third has nothing. Resistance to ground is 3,1 Ohms, which should be ok, but when I measure in continuity mode from ground to one side of the coil the multimeter beeps. Could be because the treshold is so low that it actually gives it as short.
This coil is for 1V_VCCGT which should be for the iGPU, maybe will only power up when iGPU is on load

Motherboard is FAROE DIS X32 MB MV (18742-1 0GG02)

Best Regards

You're absolutely right in all your observations.

Boot and run in safe mode to check if the unit is more stable.

No luck there, tried even with a different M.2 and when trying to install windows it freezes. Tried also with Linux and same story

There were 2 tantalum 330uf capacitors near the coils that were in the two hundreed ish. Replace those also but still the same. I'm guessing that this CPU is faulty...

Maybe cpu got hit by DRMOS failure. It often leads to a bad cpu.But since you are getting display, i beleive this is not the case here. Physical inspection under microscope done? Its a good idea to flash clean me bios also. Another issue could be with ram circuit-Check ram slots carefully and if possible try with another dimm stick.

Already tried different ram sticks in both slots. Maybe is when CPU goes on boost or something it fails. As there's no other way to swap CPU's as in old days - go figure...
Just unfortunate!!!
