Hello guys,
I'm having trouble with this HP Pavilion Gaming, it has a discrete nvidia GPU, but it is not shown or recognized by device manager, i already update the BIOS to the last version, tried many drivers and there is no results.
Well, now I'm working on the mainboard, there is no VGA_CORE voltage
+19VB_GPU_FVDD is present.
+0.95VS_VCCIOP is present
+1.35VSDGPU not present.
+VGA_CORE not present.
VGA_CORE resistance to ground 1.2 ohm
I don't have schematic for this model, just the boardview (below)
It is my first try reparing a discrete GPU related problem, i see many signals but I don't know which one comes first.
