First thing

Check rtc section
Do hard reset
Re flash good bios or verify rsmrst#

Things like this typically mean the KBC software is running, and there is something the KBC doesn't like. As stingerchamp said, do basic checks first.

Check resistances on all the coils. I assume the schematic for this doesnt exist?

i have schem

Then publish it. I found the one for rev 2.0 but 1.1 seems to be on paysites only

Im having a low impedance on this coil I cant I identify where to find it in the schematic.

Very simple, identify the IC next to it. If this is feeding a big chip like the CPU it may very well be the normal resistance for that rail.
